A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.
From Django documentation for url
url(regex, view, kwargs=None, name=None)
This function is an alias todjango.urls.re_path()
. It’s likely to be deprecated in a future release.
Key difference between path
and re_path
is that path
uses route without regex
You can use re_path
for complex regex calls and use just path
for simpler lookups
Just activate your virtual environment.
There is a button Download ZIP
. If you want to do a sparse checkout there are many solutions on the site. For example here.
Step-1
Please define a method in Api interface like:-
@FormUrlEncoded
@POST()
Call<RootLoginModel> getForgotPassword(
@Url String apiname,
@Field(ParameterConstants.email_id) String username
);
Step-2 For a best practice define a class for retrofit instance:-
public class ApiRequest {
static Retrofit retrofit = null;
public static Retrofit getClient() {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient okHttpClient = new OkHttpClient().newBuilder()
.addInterceptor(logging)
.connectTimeout(60, TimeUnit.SECONDS)
.readTimeout(60, TimeUnit.SECONDS)
.writeTimeout(60, TimeUnit.SECONDS)
.build();
if (retrofit==null) {
retrofit = new Retrofit.Builder()
.baseUrl(URLConstants.base_url)
.client(okHttpClient)
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}
} Step-3 define in your activity:-
final APIService request =ApiRequest.getClient().create(APIService.class);
Call<RootLoginModel> call = request.getForgotPassword("dynamic api
name",strEmailid);
HttpClient is not supported in sdk 23 and 23+.
If you need to use into sdk 23, add below code to your gradle:
android {
useLibrary 'org.apache.http.legacy'
}
Its working for me. Hope useful for you.
There is an option in Postman if you download it from https://www.getpostman.com instead of the chrome store (most probably it has been introduced in the new versions and the chrome one will be updated later) not sure about the old ones.
In the settings, turn off the SSL certificate verification option
Be sure to remember to reactivate it afterwards, this is a security feature.
If you really want to use the chrome app, you could always add an exception to chrome for the url: Enter the url you would like to open in the chrome browser, you'll get a warning with a link at the bottom of the page to add an exception, which if you do, it will also allow postman to access your url. But the first option of using the postman stand-alone app is much better.
I hope this can help.
If you're on Digital Ocean this means you need to go to /etc/nginx/sites-enabled/ and then REMOVE using rm -R digitalocean and default
It fixed it for me!
jww is right — you're referencing the wrong intermediate certificate.
As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt
/etc/nginx/nginx.conf
sudo chown -R nginx:nginx /var/lib/nginx
Now see the magic.
set one more property curl_setopt($ch, CURLOPT_SSL_VERIFYPEER , false);
You can make PHP and JavaScript work together by generating the following line in each page template:
<script>
document.mybaseurl='<?php echo base_url('assets/css/themes/default.css');?>';
</script>
Then you can refer to document.mybaseurl anywhere in your JavaScript. This saves you some debugging and complexity because this variable is always consistent with the PHP calculation.
Here my solution:
root@fiq:/home/django/django_project# chmod 777 db.sqlite3
root@fiq:/home/django/django_project# cd ..
root@fiq:/home/django# chmod 777 *
Go to <'your_website/admin'>
put username and password.. That's it.
Change CI index.php file to:
if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
define('ENVIRONMENT', 'development');
} else {
define('ENVIRONMENT', 'production');
}
if (defined('ENVIRONMENT')){
switch (ENVIRONMENT){
case 'development':
error_reporting(E_ALL);
break;
case 'testing':
case 'production':
error_reporting(0);
break;
default:
exit('The application environment is not set correctly.');
}
}
IF PHP errors are off, but any MySQL errors are still going to show, turn these off in the /config/database.php file. Set the db_debug option to false:
$db['default']['db_debug'] = FALSE;
Also, you can use active_group as development and production to match the environment https://www.codeigniter.com/user_guide/database/configuration.html
$active_group = 'development';
$db['development']['hostname'] = 'localhost';
$db['development']['username'] = '---';
$db['development']['password'] = '---';
$db['development']['database'] = '---';
$db['development']['dbdriver'] = 'mysql';
$db['development']['dbprefix'] = '';
$db['development']['pconnect'] = TRUE;
$db['development']['db_debug'] = TRUE;
$db['development']['cache_on'] = FALSE;
$db['development']['cachedir'] = '';
$db['development']['char_set'] = 'utf8';
$db['development']['dbcollat'] = 'utf8_general_ci';
$db['development']['swap_pre'] = '';
$db['development']['autoinit'] = TRUE;
$db['development']['stricton'] = FALSE;
$db['production']['hostname'] = 'localhost';
$db['production']['username'] = '---';
$db['production']['password'] = '---';
$db['production']['database'] = '---';
$db['production']['dbdriver'] = 'mysql';
$db['production']['dbprefix'] = '';
$db['production']['pconnect'] = TRUE;
$db['production']['db_debug'] = FALSE;
$db['production']['cache_on'] = FALSE;
$db['production']['cachedir'] = '';
$db['production']['char_set'] = 'utf8';
$db['production']['dbcollat'] = 'utf8_general_ci';
$db['production']['swap_pre'] = '';
$db['production']['autoinit'] = TRUE;
$db['production']['stricton'] = FALSE;
The problem is that '_' underscores are not valid in header attribute. If removing the underscore is not an option you can add to the server block:
underscores_in_headers on;
This is basically a copy and paste from @kishorer747 comment on @Fleshgrinder answer, and solution is from: https://serverfault.com/questions/586970/nginx-is-not-forwarding-a-header-value-when-using-proxy-pass/586997#586997
I added it here as in my case the application behind nginx was working perfectly fine, but as soon ngix was between my flask app and the client, my flask app would not see the headers any longer. It was kind of time consuming to debug.
I encountered similar error
--- "403 Forbidden" in the webpage
--- "13: Permission denied" in the error log at /var/log/nginx/error.log
Below 3 Steps worked for me:
user1@comp1:/home/www/
So, my user name is "user1" (from above)
# user www-data;
user user1;
sudo nginx -s reload
Additionally, I have applied file/folder permissions (before I did above 3 steps)
(755 to my directory, say /dir1/) & (644 for files under that directory):
(I am not sure, if this additional step is really required, just above 3 steps might be enough):
chmod 755 ./dir1/
chmod 644 ./dir1/*.*
Hope this helps quick someone. Best of luck.
I think your all setting is good but you doing to misplace your htaccess file go and add your htaccess to your project file
project_folder->htaccess
and add this code to your htaccess
RewriteEngine on
RewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
First of all check your assets, it might be possible there is some error in pre-compiling of assets.
To pre-compile assets in production ENV run this command:
RAILS_ENV=production rake assets:precompile
If it shows error, remove that first,
In case of "undefined variable" error, load that variable file before using it in another file.
example:
@import "variables";
@import "style";
in application.rb file set sequence of pre-compiliation of assets
example:
config.assets.precompile += [ 'application.js', 'admin.js', 'admin/events.js', 'admin/gallery.js', 'frontendgallery.js']
config.assets.precompile += [ 'application.css', 'admin.css','admin/events.css', 'admin/gallery.css', 'frontendgallery.css']
I fond that executing click()
event on a
element inside a for loop
for multiple files download works only for limited number of files (10 files in my case). The only reason that would explain this behavior that made sense to me, was speed/intervals of downloads executed by click()
events.
I figure out that, if I slow down execution of click()
event, then I will be able to downloads all files.
This is solution that worked for me.
var urls = [
'http://example.com/file1',
'http://example.com/file2',
'http://example.com/file3'
]
var interval = setInterval(download, 300, urls);
function download(urls) {
var url = urls.pop();
var a = document.createElement("a");
a.setAttribute('href', url);
a.setAttribute('download', '');
a.setAttribute('target', '_blank');
a.click();
if (urls.length == 0) {
clearInterval(interval);
}
}
I execute download event click()
every 300ms. When there is no more files to download urls.length == 0
then, I execute clearInterval
on interval
function to stop downloads.
The key here is keep option of wsimport. And it is configured using element in About keep from the wsimport documentation :
-keep keep generated files
settings.py:
DEBUG = False
TEMPLATE_DEBUG = DEBUG
ALLOWED_HOSTS = ['localhost'] #provide your host name
and just add your 404.html
and 500.html
pages in templates folder.
remove 404.html
and 500.html
from templates in polls app.
Just reset the password, this will work.
We also had to develop a solution which would even work with APIs requiring authentication (see this article)
Using AngularJS in a nutshell here is how we did it:
Step 1: Create a dedicated directive
// jQuery needed, uses Bootstrap classes, adjust the path of templateUrl
app.directive('pdfDownload', function() {
return {
restrict: 'E',
templateUrl: '/path/to/pdfDownload.tpl.html',
scope: true,
link: function(scope, element, attr) {
var anchor = element.children()[0];
// When the download starts, disable the link
scope.$on('download-start', function() {
$(anchor).attr('disabled', 'disabled');
});
// When the download finishes, attach the data to the link. Enable the link and change its appearance.
scope.$on('downloaded', function(event, data) {
$(anchor).attr({
href: 'data:application/pdf;base64,' + data,
download: attr.filename
})
.removeAttr('disabled')
.text('Save')
.removeClass('btn-primary')
.addClass('btn-success');
// Also overwrite the download pdf function to do nothing.
scope.downloadPdf = function() {
};
});
},
controller: ['$scope', '$attrs', '$http', function($scope, $attrs, $http) {
$scope.downloadPdf = function() {
$scope.$emit('download-start');
$http.get($attrs.url).then(function(response) {
$scope.$emit('downloaded', response.data);
});
};
}]
});
Step 2: Create a template
<a href="" class="btn btn-primary" ng-click="downloadPdf()">Download</a>
Step 3: Use it
<pdf-download url="/some/path/to/a.pdf" filename="my-awesome-pdf"></pdf-download>
This will render a blue button. When clicked, a PDF will be downloaded (Caution: the backend has to deliver the PDF in Base64 encoding!) and put into the href. The button turns green and switches the text to Save. The user can click again and will be presented with a standard download file dialog for the file my-awesome.pdf.
Our example uses PDF files, but apparently you could provide any binary format given it's properly encoded.
I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.
The following example demonstrates how to POST a JSON via WebClient.UploadString Method:
var vm = new { k = "1", a = "2", c = "3", v= "4" };
using (var client = new WebClient())
{
var dataString = JsonConvert.SerializeObject(vm);
client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
client.UploadString(new Uri("http://www.contoso.com/1.0/service/action"), "POST", dataString);
}
Prerequisites: Json.NET library
You already have what you need, with a minor syntax change:
<a href="www.mysite.com" onclick="return theFunction();">Item</a>
<script type="text/javascript">
function theFunction () {
// return true or false, depending on whether you want to allow the `href` property to follow through or not
}
</script>
The default behavior of the <a>
tag's onclick
and href
properties is to execute the onclick
, then follow the href
as long as the onclick
doesn't return false
, canceling the event (or the event hasn't been prevented)
you can use like this
private dynamic defaultReminder => reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:
When location matches the last part of the directive’s value: it is better to use the root directive instead:
which would yield:
server {
listen 8080;
server_name www.mysite.com mysite.com;
error_log /home/www-data/logs/nginx_www.error.log;
error_page 404 /404.html;
location /public/doc/ {
autoindex on;
root /home/www-data/mysite;
}
location = /404.html {
root /home/www-data/mysite/static/html;
}
}
this is for server nd live site i apply in hostinger.com and its working fine
1st : $config['base_url'] = 'http://yoursitename.com';
(in confing.php)
2) : src="<?=base_url()?>assest/js/wow.min.js"
(in view file )
3) : href="<?php echo base_url()?>index.php/Mycontroller/Method"
(for url link or method calling )
Using WAMP click on wamp icon ->apache->apache modules->scroll and check rewrite_module Restart a LoadModule rewrite_module
Note, the server application restarts automatically for you once you enable "rewrite_module"
use dirname(__FILE__)
in a global configuration file.
Maybe I am biased, but I quite like my solution as it doesn't do any transforming, regex's etc and it's has the least amount of code :)
This works for a site hosted as a Virtual Directory in a IIS Web Site and as a root website on IIS
So I created an Implentation of IItemTransform
encapsulated the CssRewriteUrlTransform
and used VirtualPathUtility
to fix the path and call the existing code:
/// <summary>
/// Is a wrapper class over CssRewriteUrlTransform to fix url's in css files for sites on IIS within Virutal Directories
/// and sites at the Root level
/// </summary>
public class CssUrlTransformWrapper : IItemTransform
{
private readonly CssRewriteUrlTransform _cssRewriteUrlTransform;
public CssUrlTransformWrapper()
{
_cssRewriteUrlTransform = new CssRewriteUrlTransform();
}
public string Process(string includedVirtualPath, string input)
{
return _cssRewriteUrlTransform.Process("~" + VirtualPathUtility.ToAbsolute(includedVirtualPath), input);
}
}
//App_Start.cs
public static void Start()
{
BundleTable.Bundles.Add(new StyleBundle("~/bundles/fontawesome")
.Include("~/content/font-awesome.css", new CssUrlTransformWrapper()));
}
Seems to work fine for me?
For someone doing everything described here and still can't access:
XAMPP with Apache HTTP Server 2.4:
In file httpd-vhost.conf:
<VirtualHost *>
DocumentRoot "D:/xampp/htdocs/dir"
ServerName something.dev
<Directory "D:/xampp/htdocs/dir">
Require all granted #apache v 2.4.4 uses just this
</Directory>
</VirtualHost>
There isn't any need for a port, or an IP address here. Apache configures it on its own files. There isn't any need for NameVirtualHost *:80; it's deprecated. You can use it, but it doesn't make any difference.
Then to edit hosts, you must run Notepad as administrator (described bellow). If you were editing the file without doing this, you are editing a pseudo file, not the original (yes, it saves, etc., but it's not the real file)
In Windows:
Find the Notepad icon, right click, run as administrator, open file, go to C:/WINDOWS/system32/driver/etc/hosts, check "See all files", and open hosts.
If you where editing it before, probably you will see it's not the file you were previously editing when not running as administrator.
Then to check if Apache is reading your httpd-vhost.conf, go to folder xampFolder/apache/bin, Shift + right click, open a terminal command here, open XAMPP (as you usually do), start Apache, and then on the command line, type httpd -S
. You will see a list of the virtual hosts. Just check if your something.dev is there.
If you're seeing 403 errors in your browser console, check your MVC Bundle Config. Bundle names should not match any existing folder names in your project.
eg.
bundles.Add(new StyleBundle("~/Content/css")...
...would cause issues for IIS if the folder structure $(ProjectDir)\Content\css exists in your project, since it tries to look within the existing folder for bundle content that's not there.
Instead just use something like:
bundles.Add(new StyleBundle("~/Content/cssbundle")...
json_encode
will always add slashes.
Check some examples on the manual HERE
This is because if there are some characters which needs to escaped then they will create problem.
To use the json please Parse your json to ensure that the slashes are removed
Well whether or not you remove slashesthe json will be parsed without any problem by eval.
<?php
$array = array('url'=>'http://mysite.com/uploads/gallery/7f/3b/f65ab8165d_logo.jpeg','id'=>54);
?>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
<script type="text/javascript">
var x = jQuery.parseJSON('<?php echo json_encode($array);?>');
alert(x);
</script>
This is my code and i m able to parse the JSON.
Check your code May be you are missing something while parsing the JSON
Give permission in .htaccess as follows:
<Directory "Your directory path/uploads/">
Allow from all
</Directory>
Double quote (" ") the entire URL
.It works.
curl "http://www.mysite.com?name=john&passwd=@31&3*J"
You can include this directly in your buttun. It works very well. I hope it'll be useful for you.
onclick="setTimeout('location.href = ../../dashboard.xhtml
;', 7000);"
from os.path import dirname, realpath, join
join(dirname(realpath(dirname(__file__))), 'templates')
Update:
If you happen to "copy" settings.py
through symlinking, @forivall's answer is better:
~user/
project1/
mysite/
settings.py
templates/
wrong.html
project2/
mysite/
settings.py -> ~user/project1/settings.py
templates/
right.html
The method above will 'see' wrong.html
while @forivall's method will see right.html
In the absense of symlinks the two answers are identical.
If you are using windows, just run .\Scripts\activate. Mind that the backslash plays the trick!
URL url = new URL("https://www.google.com");
//if you are using
URLConnection conn =url.openConnection();
//change it to

This made my life so much easier. You basically put in your elements id tag and its scrolls to it without a lot of code

I have tried all the solutions above, but the following solved my problem
chcon -R -t httpd_sys_rw_content_t your_file_directory
Redirect non-www to www
For Single Domain :
server {
server_name example.com;
return 301 $scheme://www.example.com$request_uri;
}
For All Domains :
server {
server_name "~^(?!www\.).*" ;
return 301 $scheme://www.$host$request_uri;
}
Redirect www to non-www For Single Domain:
server {
server_name www.example.com;
return 301 $scheme://example.com$request_uri;
}
For All Domains :
server {
server_name "~^www\.(.*)$" ;
return 301 $scheme://$1$request_uri ;
}
My fix was as simple as making sure the correct connection string was in ALL appsettings.json files, not just the default one.
I had a similar problem when using TFS 2017. I was not able to push or pull GIT repositories. Eventually I reinstalled TFS 2017, making sure that I installed TFS 2017 with an SSH Port different from 22 (in my case, I chose 8022). After that, push and pull became possible against TFS using SSH.
A solution without Regex, a little bit easier on the eye, one I was looking for
This supports ports, hash parameters etc.
Uses browsers attribute element as a parser.
function setUrlParameters(url, parameters) {
var parser = document.createElement('a');
parser.href = url;
url = "";
if (parser.protocol) {
url += parser.protocol + "//";
}
if (parser.host) {
url += parser.host;
}
if (parser.pathname) {
url += parser.pathname;
}
var queryParts = {};
if (parser.search) {
var search = parser.search.substring(1);
var searchParts = search.split("&");
for (var i = 0; i < searchParts.length; i++) {
var searchPart = searchParts[i];
var whitespaceIndex = searchPart.indexOf("=");
if (whitespaceIndex !== -1) {
var key = searchPart.substring(0, whitespaceIndex);
var value = searchPart.substring(whitespaceIndex + 1);
queryParts[key] = value;
} else {
queryParts[searchPart] = false;
}
}
}
var parameterKeys = Object.keys(parameters);
for (var i = 0; i < parameterKeys.length; i++) {
var parameterKey = parameterKeys[i];
queryParts[parameterKey] = parameters[parameterKey];
}
var queryPartKeys = Object.keys(queryParts);
var query = "";
for (var i = 0; i < queryPartKeys.length; i++) {
if (query.length === 0) {
query += "?";
}
if (query.length > 1) {
query += "&";
}
var queryPartKey = queryPartKeys[i];
query += queryPartKey;
if (queryParts[queryPartKey]) {
query += "=";
query += queryParts[queryPartKey];
}
}
url += query;
if (parser.hash) {
url += parser.hash;
}
return url;
}
Here it is. Add this code to your web.config file:
<system.webServer>
<rewrite>
<rules>
<rule name="Root Hit Redirect" stopProcessing="true">
<match url="^$" />
<action type="Redirect" url="/menu_1/MainScreen.aspx" />
</rule>
</rules>
</rewrite>
</system.webServer>
It will do 301 Permanent Redirect (URL will be changed in browser). If you want to have such "redirect" to be invisible (rewrite, internal redirect), then use this rule (the only difference is that "Redirect" has been replaced by "Rewrite"):
<system.webServer>
<rewrite>
<rules>
<rule name="Root Hit Redirect" stopProcessing="true">
<match url="^$" />
<action type="Rewrite" url="/menu_1/MainScreen.aspx" />
</rule>
</rules>
</rewrite>
</system.webServer>
SimpleConfigFile is a library that does exactly what you require and it is very simple to use.
# File file.cfg
url = http://example.com
file = main.exe
true = 0
The following program reads the previous configuration file:
#include<iostream>
#include<string>
#include<vector>
#include "config_file.h"
int main(void)
{
// Variables that we want to read from the config file
std::string url, file;
bool true_false;
// Names for the variables in the config file. They can be different from the actual variable names.
std::vector<std::string> ln = {"url","file","true"};
// Open the config file for reading
std::ifstream f_in("file.cfg");
CFG::ReadFile(f_in, ln, url, file, true_false);
f_in.close();
std::cout << "url: " << url << std::endl;
std::cout << "file: " << file << std::endl;
std::cout << "true: " << true_false << std::endl;
return 0;
}
The function CFG::ReadFile
uses variadic templates. This way, you can pass the variables you want to read and the corresponding type is used for reading the data in the appropriate way.
First of all you can't make a POST request using JSONP.
What basically is happening is that dynamically a script tag is inserted to load your data. Therefore only GET requests are possible.
Furthermore your data has to be wrapped in a callback function which is called after the request is finished to load the data in a variable.
This whole process is automated by jQuery for you. Just using $.getJSON on an external domain doesn't always work though. I can tell out of personal experience.
The best thing to do is adding &callback=? to you url.
At the server side you've got to make sure that your data is wrapped in this callback function.
ie.
echo $_GET['callback'] . '(' . $data . ')';
EDIT:
Don't have enough rep yet to comment on Liam's answer so therefore the solution over here.
Replace Liam's line
echo "{'fullname' : 'Jeff Hansen'}";
with
echo $_GET['callback'] . '(' . "{'fullname' : 'Jeff Hansen'}" . ')';
For those working with ant
, I use this to indicate a pause of 5 seconds:
<tr>
<td>pause</td>
<td>5000</td>
<td></td>
</tr>
That is, target: 5000
and value
empty. As the reference indicates:
pause(waitTime)
Arguments:
- waitTime - the amount of time to sleep (in milliseconds)
Wait for the specified amount of time (in milliseconds)
This is achieved through URL rewriting, not through URL obfuscating, which can't be done.
Another way to do this, as has been mentioned is by changing the hashtag, with
window.location.hash = "/2131/"
If you look at the documentation you can take just the properties you're interested in from the window
object i.e.
protocol + '//' + hostname + pathname
I reference all the methods.
Encode the query twice is the fast solution.
const query = a=123&b=456;
const url = `https://example.com/test?${encodeURIComponent(encodeURIComponent(query),)}`;
const twitterSharingURL=`https://twitter.com/intent/tweet?&url=${url}`
No, how you are doing it is correct.

jQuery way to change value on text input field is:
$('#colorpickerField1').attr('value', '#000000')
this will change attribute value
for the DOM element with ID #colorpickerField1
from #EEEEEE
to #000000
Do I need to setup specific URLconf patters for uploaded media?
Yes. For development, it's as easy as adding this to your URLconf:
if settings.DEBUG:
urlpatterns += patterns('django.views.static',
(r'media/(?P<path>.*)', 'serve', {'document_root': settings.MEDIA_ROOT}),
)
However, for production, you'll want to serve the media using Apache, lighttpd, nginx, or your preferred web server.
Try using this code for v3:
gMap = new google.maps.Map(document.getElementById('map'));
gMap.setZoom(13); // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);
You can save Base64 directly into file:
string filePath = "MyImage.jpg";
File.WriteAllBytes(filePath, Convert.FromBase64String(base64imageString));
In case, you are using Ubuntu/Lubuntu 13.04 or Ubuntu 13.10 and having problem with "/usr/bin/ld: cannot find -lz", you may need also install zlib1g-dev package:

You will need to link to the file relative to the file that includes eventManager.php
(Page A)
Change your code from
require_once('../includes/dbconn.inc');
To
require_once('../mysite/php/includes/dbconn.inc');
OK, here are the things that come into mind:
my WCF web service calls another ASMX web service, installed on a **different** web server
Ntlm
to Windows
and test again.OK, a few words on impersonation. Basically it is a known issue that you cannot use the impersonation tokens that you got to one server, to pass to another server. The reason seems to be that the token is a kind of a hash using user's password and valid for the machine generated from so it cannot be used from the middle server.
Delegation is possible under WCF (i.e. forwarding impersonation from a server to another server). Look at this topic here.
Had a directory by the same name as the file i was trying to write, so people can look out for that as well.
A simpler approach relies on redirection from the page LOGIN_REDIRECT_URL. The key thing to realize is that the user information is automatically included in the request.
Suppose:
LOGIN_REDIRECT_URL = '/profiles/home'
and you have configured a urlpattern:
(r'^profiles/home', home),
Then, all you need to write for the view home()
is:
from django.http import HttpResponseRedirect
from django.urls import reverse
from django.contrib.auth.decorators import login_required
@login_required
def home(request):
return HttpResponseRedirect(
reverse(NAME_OF_PROFILE_VIEW,
args=[request.user.username]))
where NAME_OF_PROFILE_VIEW
is the name of the callback that you are using. With django-profiles, NAME_OF_PROFILE_VIEW
can be 'profiles_profile_detail'.
You need to give a relative file path of <a href="../index.html">Home</a>
Alternately you can specify a link from the root of your site with
<a href="/pages/en/index.html">Home</a>
..
and .
have special meanings in file paths, ..
means up one directory and .
means current directory.
so <a href="index.html">Home</a>
is the same as <a href="./index.html">Home</a>
I fixed this by passing the redirect url to the FacebookRedirectLoginHelper::getAccessToken()
in my callback function:
Changing from
try {
$accessToken = $helper->getAccessToken();
}
...
to
try {
$accessToken = $helper->getAccessToken($fbRedirectUrl);
}
...
I am developing on a vagrant box, and it seems FacebookRedirectLoginHelper::getCurrentUrl()
had issues generating a valid url.
From: http://jquery-howto.blogspot.com/2009/09/get-url-parameters-values-with-jquery.html
This is what you need :)
The following code will return a JavaScript Object containing the URL parameters:
// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
For example, if you have the URL:
http://www.example.com/?me=myValue&name2=SomeOtherValue
This code will return:
{
"me" : "myValue",
"name2" : "SomeOtherValue"
}
and you can do:
var me = getUrlVars()["me"];
var name2 = getUrlVars()["name2"];
here is a short one liner to accomplish this:
request.META.get('HTTP_X_FORWARDED_FOR', request.META.get('REMOTE_ADDR', '')).split(',')[0].strip()
for me also the file_exists() function is not working properly. So I got this alternative solution. Hope this one help someone
$path = 'http://localhost/admin/public/upload/video_thumbnail/thumbnail_1564385519_0.png';
if (@GetImageSize($path)) {
echo 'File exits';
} else {
echo "File doesn't exits";
}
Here is a CSV action result I wrote that takes a DataTable and converts it into CSV. You can return this from your view and it will prompt the user to download the file. You should be able to convert this easily into a List compatible form or even just put your list into a DataTable.

I couldnt get previous solution to work but I found out that if I set the iframe scr with for example http:otherdomain.com/page.htm?from=thisdomain.com/thisfolder
then I could, in the iframe extract thisdomain.com/thisfolder
by using following javascript:
var myString = document.location.toString();
var mySplitResult = myString.split("=");
fromString = mySplitResult[1];
You can't. A redirect requires a webserver to accept the first request and send back the redirect. The "hosts" file just lets you set your own DNS records.
function include(file){
return new Promise(function(resolve, reject){
var script = document.createElement('script');
script.src = file;
script.type ='text/javascript';
script.defer = true;
document.getElementsByTagName('head').item(0).appendChild(script);
script.onload = function(){
resolve()
}
script.onerror = function(){
reject()
}
})
/*I HAVE MODIFIED THIS TO BE PROMISE-BASED
HOW TO USE THIS FUNCTION
include('js/somefile.js').then(function(){
console.log('loaded');
},function(){
console.log('not loaded');
})
*/
}
I have made django-templated-email in an effort to solve this problem, inspired by this solution (and the need to, at some point, switch from using django templates to using a mailchimp etc. set of templates for transactional, templated emails for my own project). It is still a work-in-progress though, but for the example above, you would do:
from templated_email import send_templated_mail
send_templated_mail(
'email',
'[email protected]',
['[email protected]'],
{ 'username':username }
)
With the addition of the following to settings.py (to complete the example):
TEMPLATED_EMAIL_DJANGO_SUBJECTS = {'email':'hello',}
This will automatically look for templates named 'templated_email/email.txt' and 'templated_email/email.html' for the plain and html parts respectively, in the normal django template dirs/loaders (complaining if it cannot find at least one of those).
I had the same problem, there was no extension=php_soap.dll in my php.ini But this was because I had copied the php.ini from a old and previous php version (not a good idea). I found the dll in the ext directory so I just could put it myself into the php.ini extension=php_soap.dll After Apache restart all worked with soap :)
We had a MVC application moved to a new server. .NET 4 and MVC 3 was installed, but we still got “Error 403.14". In this case, this meant that IIS did not understand that it was dealing with a MVC application, it was looking for the default page.
The solution was simple: HTTP Redirection was not installed on the server.
Server Manager – Roles – Web Server (IIS) – Roles Services – HTTP Redirection: Not installed. Installed it, problem solved.
I just deleted the file from within VS, then from 'Repository Explorer', I copied the file to the working copy.
You have to do following steps.
Go to IIS ->
Sites->
Click on Your Web site ->
In Action Click on Edit Permissions ->
Security ->
Click on ADD ->
Advanced ->
Find Now ->
Add all the users in it ->
and grant all permissions to other users ->
click on Ok.
If you do above things properly you can access your web site by using your domain.
Suggestion - Do not add host name to your site it creates problem sometime. So please host your web site using your machines ip address.
function parseQuery(queryString) {
var query = {};
var pairs = (queryString[0] === '?' ? queryString.substr(1) : queryString).split('&');
for (var i = 0; i < pairs.length; i++) {
var pair = pairs[i].split('=');
query[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1] || '');
}
return query;
}
Turns query string like hello=1&another=2
into object {hello: 1, another: 2}
. From there, it's easy to extract the variable you need.
That said, it does not deal with array cases such as "hello=1&hello=2&hello=3"
. To work with this, you must check whether a property of the object you make exists before adding to it, and turn the value of it into an array, pushing any additional bits.
array_key_exists() is SLOW compared to isset(). A combination of these two (see below code) would help.
It takes the performance advantage of isset() while maintaining the correct checking result (i.e. return TRUE even when the array element is NULL)
if (isset($a['element']) || array_key_exists('element', $a)) {
//the element exists in the array. write your code here.
}
The benchmarking comparison: (extracted from below blog posts).
array_key_exists() only : 205 ms
isset() only : 35ms
isset() || array_key_exists() : 48ms
See http://thinkofdev.com/php-fast-way-to-determine-a-key-elements-existance-in-an-array/ and http://thinkofdev.com/php-isset-and-multi-dimentional-array/
for detailed discussion.
Port: In simple language, "Port" is a number used by a particular software to identify its data coming from internet.
Each software, like Skype, Chrome, Youtube has its own port number and that's how they know which internet data is for itself.
Socket: "IP address and Port " together is called "Socket". It is used by another computer to send data to one particular computer's particular software.
IP address is used to identify the computer and Port is to identify the software such as IE, Chrome, Skype etc.
In every home, there is one mailbox and multiple people. The mailbox is a host. Your own home mailbox is a localhost. Each person in a home has a room. All letters for that person are sent to his room, hence the room number is a port.
i realize it works after adding a slash behind like so
mysite/Controller/Action/21-9-2009 10:20/
Here's the config for ISAPI_Rewrite 3:
RewriteBase /
RewriteCond %{HTTP_HOST} ^mysite.org.uk$ [NC]
RewriteRule ^stuff/(.+)$ http://stuff.mysite.org.uk/$1 [NC,R=301,L]
In most cases the slug should not change, so you really only want to calculate it on first save:
class Test(models.Model):
q = models.CharField(max_length=30)
s = models.SlugField(editable=False) # hide from admin
def save(self):
if not self.id:
self.s = slugify(self.q)
super(Test, self).save()
Before HTML5 we can use:
parent.location.hash = "hello";
and:
window.location.replace("http:www.example.com");
This method will reload your page, but HTML5 introduced the history.pushState(page, caption, replace_url)
that should not reload your page.
If your directory structure is like this,
site
application
controller
folder_1
first_controller.php
second_controller.php
folder_2
first_controller.php
second_controller.php
And when you are going to redirect it in same controller in which you are working then just write the following code.
$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
redirect('same_controller/method', 'refresh');
}
And if you want to redirect to another control then use the following code.
$this->load->helper('url');
if ($some_value === FALSE/TRUE) //You may give 0/1 as well,its up to your logic
{
redirect('folder_name/any_controller_name/method', 'refresh');
}
As the error message says in the last line: the module models
in the file c:\projects\mysite..\mysite\polls\models.py
contains no class model
. This error occurs in the definition of the Poll
class:
class Poll(models.model):
Either the class model
is misspelled in the definition of the class Poll
or it is misspelled in the module models
. Another possibility is that it is completely missing from the module models
. Maybe it is in another module or it is not yet implemented in models
.
Wget 1.18 may work better, e.g., I got bitten by a version 1.12 bug where...
wget --recursive (...)
...only retrieves index.html instead of all files.
Workaround was to notice some 301 redirects and try the new location — given the new URL, wget got all the files in the directory.

EDIT: Okay, so you don't want your local time (which isn't Australia) to contribute to the result, but instead the Australian time zone. Your existing code should be absolutely fine then, although Sydney is currently UTC+11, not UTC+10.. Short but complete test app:
import java.util.*;
import java.text.*;
public class Test {
public static void main(String[] args) throws InterruptedException {
Date date = new Date(1318386508000L);
DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
String formatted = format.format(date);
System.out.println(formatted);
format.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));
formatted = format.format(date);
System.out.println(formatted);
}
}
Output:
12/10/2011 02:28:28
12/10/2011 13:28:28
I would also suggest you start using Joda Time which is simply a much nicer date/time API...
EDIT: Note that if your system doesn't know about the Australia/Sydney
time zone, it would show UTC. For example, if I change the code about to use TimeZone.getTimeZone("blah/blah")
it will show the UTC value twice. I suggest you print TimeZone.getTimeZone("Australia/Sydney").getDisplayName()
and see what it says... and check your code for typos too :)
Yet another tree structure:
public class TreeNode<T> : IEnumerable<TreeNode<T>>
{
public T Data { get; set; }
public TreeNode<T> Parent { get; set; }
public ICollection<TreeNode<T>> Children { get; set; }
public TreeNode(T data)
{
this.Data = data;
this.Children = new LinkedList<TreeNode<T>>();
}
public TreeNode<T> AddChild(T child)
{
TreeNode<T> childNode = new TreeNode<T>(child) { Parent = this };
this.Children.Add(childNode);
return childNode;
}
... // for iterator details see below link
}
Sample usage:
TreeNode<string> root = new TreeNode<string>("root");
{
TreeNode<string> node0 = root.AddChild("node0");
TreeNode<string> node1 = root.AddChild("node1");
TreeNode<string> node2 = root.AddChild("node2");
{
TreeNode<string> node20 = node2.AddChild(null);
TreeNode<string> node21 = node2.AddChild("node21");
{
TreeNode<string> node210 = node21.AddChild("node210");
TreeNode<string> node211 = node21.AddChild("node211");
}
}
TreeNode<string> node3 = root.AddChild("node3");
{
TreeNode<string> node30 = node3.AddChild("node30");
}
}

I would suggest using the below method if you are trying to read the json data only.
URL requestUrl=new URL(url);
URLConnection con = requestUrl.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
StringBuilder sb=new StringBuilder();
int cp;
try {
while((cp=rd.read())!=-1){
sb.append((char)cp);
}
catch(Exception e){
}
String json=sb.toString();
I use this, works like a charm. No need to have any functions, just inline with your link(s)

How about making the <div id="mainWrapperDivWithBGImage">
as three divs, where the two outside divs hold the rounded corners images, and the middle div simply has a background-color to match the rounded corner images. Then you could simply place the other elements inside the middle div, or:
#outside_left{width:10px; float:left;}
#outside_right{width:10px; float:right;}
#middle{background-color:#color of rnd_crnrs_foo.gif; float:left;}
Then
HTML:
<div id="mainWrapperDivWithBGImage">
<div id="outside_left><img src="rnd_crnrs_left.gif" /></div>
<div id="middle">
<div id="another_div"><img src="foo.gif" /></div>
<div id="outside_right><img src="rnd_crnrs_right.gif" /></div>
</div>
You may have to do position:relative; and such.
Here's a PowerShell variant that doesn't require loading assemblies prior to creating the window, however it runs noticeably slower (~+50%) than the PowerShell MessageBox command posted here by @npocmaka:
powershell (New-Object -ComObject Wscript.Shell).Popup("""Operation Completed""",0,"""Done""",0x0)
You can change the last parameter from "0x0" to a value below to display icons in the dialog (see Popup Method for further reference):
0x10 Stop
0x20 Question Mark
0x30 Exclamation Mark
0x40 Information Mark

this : is the DOM Element $(this) : Jquery objct, which wrapped with Dom Element, you can check this answer also this vs $(this)
try like this Attr(). Get the value of an attribute for the first element in the set of matched elements.
$(document).ready(function () {
$(".inputs").click(function () {
alert(" or " + $(this).attr("id"));
});
});
The keyup event will detect if the user has cleared the box as well (i.e. backspace raises the event but backspace does not raise the keypress event in IE)
$("#inputname").keyup(function() {
if (!this.value) {
alert('The box is empty');
}});
Old question, but half a decade later, it’s worth revisiting. Here I am only discussing the selector aspect of jQuery.
document.querySelector[All]
is supported by all current browsers, down to IE8, so compatibility is no longer an issue. I have also found no performance issues to speak of (it was supposed to be slower than document.getElementById
, but my own testing suggests that it’s slightly faster).
Therefore when it comes to manipulating an element directly, it is to be preferred over jQuery.
For example:
var element=document.querySelector('h1');
element.innerHTML='Hello';
is vastly superior to:
var $element=$('h1');
$element.html('hello');
In order to do anything at all, jQuery has to run through a hundred lines of code (I once traced through code such as the above to see what jQuery was actually doing with it). This is clearly a waste of everyone’s time.
The other significant cost of jQuery is the fact that it wraps everything inside a new jQuery object. This overhead is particularly wasteful if you need to unwrap the object again or to use one of the object methods to deal with properties which are already exposed on the original element.
Where jQuery has an advantage, however, is in how it handles collections. If the requirement is to set properties of multiple elements, jQuery has a built-in each
method which allows something like this:
var $elements=$('h2'); // multiple elements
$elements.html('hello');
To do so with Vanilla JavaScript would require something like this:
var elements=document.querySelectorAll('h2');
elements.forEach(function(e) {
e.innerHTML='Hello';
});
which some find daunting.
jQuery selectors are also slightly different, but modern browsers (excluding IE8) won’t get much benefit.
As a rule, I caution against using jQuery for new projects:
If none of the above matters, then do what you will. However, jQuery is no longer as important to cross-platform development as it used to be, as modern JavaScript and CSS go a lot further than they used to.
This makes no mention of other features of jQuery. However, I think that they, too, need a closer look.
UPDATE: The original answer from 2013 is now outdated because some of the classes have been replaced. The new way of doing this is using the new java.time
classes.
DateTimeFormatter dtf = DateTimeFormatter.ofPattern("dd MM yyyy");
String inputString1 = "23 01 1997";
String inputString2 = "27 04 1997";
try {
LocalDateTime date1 = LocalDate.parse(inputString1, dtf);
LocalDateTime date2 = LocalDate.parse(inputString2, dtf);
long daysBetween = Duration.between(date1, date2).toDays();
System.out.println ("Days: " + daysBetween);
} catch (ParseException e) {
e.printStackTrace();
}
Note that this solution will give the number of actual 24 hour-days, not the number of calendar days. For the latter, use
long daysBetween = ChronoUnit.DAYS.between(date1, date2)
Original answer (outdated as of Java 8)
You are making some conversions with your Strings that are not necessary. There is a SimpleDateFormat
class for it - try this:
SimpleDateFormat myFormat = new SimpleDateFormat("dd MM yyyy");
String inputString1 = "23 01 1997";
String inputString2 = "27 04 1997";
try {
Date date1 = myFormat.parse(inputString1);
Date date2 = myFormat.parse(inputString2);
long diff = date2.getTime() - date1.getTime();
System.out.println ("Days: " + TimeUnit.DAYS.convert(diff, TimeUnit.MILLISECONDS));
} catch (ParseException e) {
e.printStackTrace();
}
EDIT: Since there have been some discussions regarding the correctness of this code: it does indeed take care of leap years. However, the TimeUnit.DAYS.convert
function loses precision since milliseconds are converted to days (see the linked doc for more info). If this is a problem, diff
can also be converted by hand:
float days = (diff / (1000*60*60*24));
Note that this is a float
value, not necessarily an int
.
If you wish to change the default configurations then follow this steps:
Open terminal type command
$ /usr/local/lib/python<2/3>.x/dist-packages/django/core/management/commands
Now open runserver.py file in nano editor as superuser
$ sudo nano runserver.py
find the 'default_port' variable then you will see the default port no is '8000'. Now you can change it to whatever you want.
Now exit and save the file using "CTRL + X and Y to save the file"
Note: Replace <2/3>.x with your usable version of python
If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?
For class and text xpath-
//div[contains(@class,'Caption') and (text(),'Model saved')]
and
For class and id xpath-
//div[contains(@class,'gwt-HTML') and @id="alertLabel"]
For New versions
Older versions of python may not have pip installed and get-pip will throw errors. Please update your python (2.7.15 as of Aug 12, 2018).
All current versions have an option to install pip and add it to the path.
Steps:
Powershell
as admin. (win+x
then a
)python -m pip install <package>
.If python is not in PATH, it'll throw an error saying unrecognized cmd. To fix, simply add it to the path as mentioned below.
[OLD Answer]
Python 2.7 must be having pip pre-installed.
Try installing your package by:
win+x
then a
)C:\Python27\Scripts
pip install "package name"
.Note: Else reinstall python: https://www.python.org/downloads/
Also note: You must be in C:\Python27\Scripts
in order to use pip command, Else add it to your path by typing:
[Environment]::SetEnvironmentVariable("Path","$env:Path;C:\Python27\;C:\Python27\Scripts\", "User")
Use a subquery in the where clause. For a delete query requirig a join, this example will delete rows that are unmatched in the joined table "docx_document" and that have a create date > 120 days in the "docs_documents" table.
delete from docs_documents d
where d.id in (
select a.id from docs_documents a
left join docx_document b on b.id = a.document_id
where b.id is null
and floor(sysdate - a.create_date) > 120
);
You can use a combination of Where and Any for finding not in:
var NotInRecord =list1.Where(p => !list2.Any(p2 => p2.Email == p.Email));
You can use this method for any minute / hour / period (aka am/pm) combination:
- (NSDate *)todayModifiedWithHours:(NSString *)hours
minutes:(NSString *)minutes
andPeriod:(NSString *)period
{
NSDate *todayModified = NSDate.date;
NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit|NSMinuteCalendarUnit fromDate:todayModified];
[components setMinute:minutes.intValue];
int hour = 0;
if ([period.uppercaseString isEqualToString:@"AM"]) {
if (hours.intValue == 12) {
hour = 0;
}
else {
hour = hours.intValue;
}
}
else if ([period.uppercaseString isEqualToString:@"PM"]) {
if (hours.intValue != 12) {
hour = hours.intValue + 12;
}
else {
hour = 12;
}
}
[components setHour:hour];
todayModified = [calendar dateFromComponents:components];
return todayModified;
}
Requested Example:
NSDate *todayAt10AM = [self todayModifiedWithHours:@"10"
minutes:@"00"
andPeriod:@"am"];
Another method to try out.
Also select
could be replaced when you set the initial column into a Range object. Performance wise it helps.
Dim rng as Range
Set rng = WorkSheets(1).Range("A1") '-- you may change the sheet name according to yours.
'-- here is your loop
i = 1
Do
'-- do something: e.g. show the address of the column that you are currently in
Msgbox rng.offset(0,i).Address
i = i + 1
Loop Until i > 10
** Two methods to get the column name using column number**
code
colName = Split(Range.Offset(0,i).Address, "$")(1)
code
Function myColName(colNum as Long) as String
myColName = Left(Range(0, colNum).Address(False, False), _
1 - (colNum > 10))
End Function
In all officially maintained versions of Python, the simplest approach is to use the subprocess.check_output
function:
>>> subprocess.check_output(['ls', '-l'])
b'total 0\n-rw-r--r-- 1 memyself staff 0 Mar 14 11:04 files\n'
check_output
runs a single program that takes only arguments as input.1 It returns the result exactly as printed to stdout
. If you need to write input to stdin
, skip ahead to the run
or Popen
sections. If you want to execute complex shell commands, see the note on shell=True
at the end of this answer.
The check_output
function works in all officially maintained versions of Python. But for more recent versions, a more flexible approach is available.
run
If you're using Python 3.5+, and do not need backwards compatibility, the new run
function is recommended by the official documentation for most tasks. It provides a very general, high-level API for the subprocess
module. To capture the output of a program, pass the subprocess.PIPE
flag to the stdout
keyword argument. Then access the stdout
attribute of the returned CompletedProcess
object:
>>> import subprocess
>>> result = subprocess.run(['ls', '-l'], stdout=subprocess.PIPE)
>>> result.stdout
b'total 0\n-rw-r--r-- 1 memyself staff 0 Mar 14 11:04 files\n'
The return value is a bytes
object, so if you want a proper string, you'll need to decode
it. Assuming the called process returns a UTF-8-encoded string:
>>> result.stdout.decode('utf-8')
'total 0\n-rw-r--r-- 1 memyself staff 0 Mar 14 11:04 files\n'
This can all be compressed to a one-liner if desired:
>>> subprocess.run(['ls', '-l'], stdout=subprocess.PIPE).stdout.decode('utf-8')
'total 0\n-rw-r--r-- 1 memyself staff 0 Mar 14 11:04 files\n'
If you want to pass input to the process's stdin
, you can pass a bytes
object to the input
keyword argument:
>>> cmd = ['awk', 'length($0) > 5']
>>> ip = 'foo\nfoofoo\n'.encode('utf-8')
>>> result = subprocess.run(cmd, stdout=subprocess.PIPE, input=ip)
>>> result.stdout.decode('utf-8')
'foofoo\n'
You can capture errors by passing stderr=subprocess.PIPE
(capture to result.stderr
) or stderr=subprocess.STDOUT
(capture to result.stdout
along with regular output). If you want run
to throw an exception when the process returns a nonzero exit code, you can pass check=True
. (Or you can check the returncode
attribute of result
above.) When security is not a concern, you can also run more complex shell commands by passing shell=True
as described at the end of this answer.
Later versions of Python streamline the above further. In Python 3.7+, the above one-liner can be spelled like this:
>>> subprocess.run(['ls', '-l'], capture_output=True, text=True).stdout
'total 0\n-rw-r--r-- 1 memyself staff 0 Mar 14 11:04 files\n'
Using run
this way adds just a bit of complexity, compared to the old way of doing things. But now you can do almost anything you need to do with the run
function alone.
check_output
If you are using an older version of Python, or need modest backwards compatibility, you can use the check_output
function as briefly described above. It has been available since Python 2.7.
subprocess.check_output(*popenargs, **kwargs)
It takes takes the same arguments as Popen
(see below), and returns a string containing the program's output. The beginning of this answer has a more detailed usage example. In Python 3.5+, check_output
is equivalent to executing run
with check=True
and stdout=PIPE
, and returning just the stdout
attribute.
You can pass stderr=subprocess.STDOUT
to ensure that error messages are included in the returned output. When security is not a concern, you can also run more complex shell commands by passing shell=True
as described at the end of this answer.
If you need to pipe from stderr
or pass input to the process, check_output
won't be up to the task. See the Popen
examples below in that case.
Popen
If you need deep backwards compatibility, or if you need more sophisticated functionality than check_output
or run
provide, you'll have to work directly with Popen
objects, which encapsulate the low-level API for subprocesses.
The Popen
constructor accepts either a single command without arguments, or a list containing a command as its first item, followed by any number of arguments, each as a separate item in the list. shlex.split
can help parse strings into appropriately formatted lists. Popen
objects also accept a host of different arguments for process IO management and low-level configuration.
To send input and capture output, communicate
is almost always the preferred method. As in:
output = subprocess.Popen(["mycmd", "myarg"],
stdout=subprocess.PIPE).communicate()[0]
Or
>>> import subprocess
>>> p = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE,
... stderr=subprocess.PIPE)
>>> out, err = p.communicate()
>>> print out
.
..
foo
If you set stdin=PIPE
, communicate
also allows you to pass data to the process via stdin
:
>>> cmd = ['awk', 'length($0) > 5']
>>> p = subprocess.Popen(cmd, stdout=subprocess.PIPE,
... stderr=subprocess.PIPE,
... stdin=subprocess.PIPE)
>>> out, err = p.communicate('foo\nfoofoo\n')
>>> print out
foofoo
Note Aaron Hall's answer, which indicates that on some systems, you may need to set stdout
, stderr
, and stdin
all to PIPE
(or DEVNULL
) to get communicate
to work at all.
In some rare cases, you may need complex, real-time output capturing. Vartec's answer suggests a way forward, but methods other than communicate
are prone to deadlocks if not used carefully.
As with all the above functions, when security is not a concern, you can run more complex shell commands by passing shell=True
.
1. Running shell commands: the shell=True
argument
Normally, each call to run
, check_output
, or the Popen
constructor executes a single program. That means no fancy bash-style pipes. If you want to run complex shell commands, you can pass shell=True
, which all three functions support. For example:
>>> subprocess.check_output('cat books/* | wc', shell=True, text=True)
' 1299377 17005208 101299376\n'
However, doing this raises security concerns. If you're doing anything more than light scripting, you might be better off calling each process separately, and passing the output from each as an input to the next, via
run(cmd, [stdout=etc...], input=other_output)
Or
Popen(cmd, [stdout=etc...]).communicate(other_output)
The temptation to directly connect pipes is strong; resist it. Otherwise, you'll likely see deadlocks or have to do hacky things like this.
When writing HTML source code, you can define attributes on your HTML elements. Then, once the browser parses your code, a corresponding DOM node will be created. This node is an object, and therefore it has properties.
For instance, this HTML element:
<input type="text" value="Name:">
has 2 attributes (type
and value
).
Once the browser parses this code, a HTMLInputElement object will be created, and this object will contain dozens of properties like: accept, accessKey, align, alt, attributes, autofocus, baseURI, checked, childElementCount, childNodes, children, classList, className, clientHeight, etc.
For a given DOM node object, properties are the properties of that object, and attributes are the elements of the attributes
property of that object.
When a DOM node is created for a given HTML element, many of its properties relate to attributes with the same or similar names, but it's not a one-to-one relationship. For instance, for this HTML element:
<input id="the-input" type="text" value="Name:">
the corresponding DOM node will have id
,type
, and value
properties (among others):
The id
property is a reflected property for the id
attribute: Getting the property reads the attribute value, and setting the property writes the attribute value. id
is a pure reflected property, it doesn't modify or limit the value.
The type
property is a reflected property for the type
attribute: Getting the property reads the attribute value, and setting the property writes the attribute value. type
isn't a pure reflected property because it's limited to known values (e.g., the valid types of an input). If you had <input type="foo">
, then theInput.getAttribute("type")
gives you "foo"
but theInput.type
gives you "text"
.
In contrast, the value
property doesn't reflect the value
attribute. Instead, it's the current value of the input. When the user manually changes the value of the input box, the value
property will reflect this change. So if the user inputs "John"
into the input box, then:
theInput.value // returns "John"
whereas:
theInput.getAttribute('value') // returns "Name:"
The value
property reflects the current text-content inside the input box, whereas the value
attribute contains the initial text-content of the value
attribute from the HTML source code.
So if you want to know what's currently inside the text-box, read the property. If you, however, want to know what the initial value of the text-box was, read the attribute. Or you can use the defaultValue
property, which is a pure reflection of the value
attribute:
theInput.value // returns "John"
theInput.getAttribute('value') // returns "Name:"
theInput.defaultValue // returns "Name:"
There are several properties that directly reflect their attribute (rel
, id
), some are direct reflections with slightly-different names (htmlFor
reflects the for
attribute, className
reflects the class
attribute), many that reflect their attribute but with restrictions/modifications (src
, href
, disabled
, multiple
), and so on. The spec covers the various kinds of reflection.
Try this
function pad (str, max) {
return str.length < max ? pad("0" + str, max) : str;
}
alert(pad("5", 2));
Example
Or
var number = 5;
var i;
if (number < 10) {
alert("0"+number);
}
Example
Let:
>>> n = 1000
>>> x = np.arange(n)
>>> reps = 10000
Zero-cost allocations
A view does not take any additional memory. Thus, these declarations are instantaneous:
# New axis
x[np.newaxis, ...]
# Broadcast to specific shape
np.broadcast_to(x, (reps, n))
Forced allocation
If you want force the contents to reside in memory:
>>> %timeit np.array(np.broadcast_to(x, (reps, n)))
10.2 ms ± 62.3 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit np.repeat(x[np.newaxis, :], reps, axis=0)
9.88 ms ± 52.4 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit np.tile(x, (reps, 1))
9.97 ms ± 77.3 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
All three methods are roughly the same speed.
Computation
>>> a = np.arange(reps * n).reshape(reps, n)
>>> x_tiled = np.tile(x, (reps, 1))
>>> %timeit np.broadcast_to(x, (reps, n)) * a
17.1 ms ± 284 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit x[np.newaxis, :] * a
17.5 ms ± 300 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
>>> %timeit x_tiled * a
17.6 ms ± 240 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)
All three methods are roughly the same speed.
Conclusion
If you want to replicate before a computation, consider using one of the "zero-cost allocation" methods. You won't suffer the performance penalty of "forced allocation".
I prefer the simplicity and flexibility of the 12 factor app recommendation for logging. To append to a log file you can use shell redirection. The default logger in Go writes to stderr (2).
./app 2>> logfile

If the command should work with both tabs and spaces as the delimiter I would use awk
:
awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile
As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for
loop:
awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile
If you want to use cut
, you need to use the -f
option:
cut -f100-105 myfile > outfile
If the field delimiter is different from TAB
you need to specify it using -d
:
cut -d' ' -f100-105 myfile > outfile
Check the man page for more info on the cut command.
I think you want this:
select *
from dbo.table
where DATALENGTH(column_name) = 3
In PL/SQL v.10
keyword declare is used to declare variable
DECLARE stupidvar varchar(20);
to assign a value you can set it when you declare
DECLARE stupidvar varchar(20) := '12345678';
or to select something into that variable you use INTO
statement, however you need to wrap statement in BEGIN
and END
, also you need to make sure that only single value is returned, and don't forget semicolons.
so the full statement would come out following:
DECLARE stupidvar varchar(20);
BEGIN
SELECT stupid into stupidvar FROM stupiddata CC
WHERE stupidid = 2;
END;
Your variable is only usable within BEGIN
and END
so if you want to use more than one you will have to do multiple BEGIN END
wrappings
DECLARE stupidvar varchar(20);
BEGIN
SELECT stupid into stupidvar FROM stupiddata CC
WHERE stupidid = 2;
DECLARE evenmorestupidvar varchar(20);
BEGIN
SELECT evenmorestupid into evenmorestupidvar FROM evenmorestupiddata CCC
WHERE evenmorestupidid = 42;
INSERT INTO newstupiddata (newstupidcolumn, newevenmorestupidstupidcolumn)
SELECT stupidvar, evenmorestupidvar
FROM dual
END;
END;
Hope this saves you some time
element.onclick = function() { /* do stuff */ }
element.addEventListener('click', function(){ /* do stuff */ },false);
They apparently do the same thing: listen for the click event and execute a callback function. Nevertheless, they’re not equivalent. If you ever need to choose between the two, this could help you to figure out which one is the best for you.
The main difference is that onclick is just a property, and like all object properties, if you write on more than once, it will be overwritten. With addEventListener() instead, we can simply bind an event handler to the element, and we can call it each time we need it without being worried of any overwritten properties. Example is shown here,
Try it: https://jsfiddle.net/fjets5z4/5/
In first place I was tempted to keep using onclick, because it’s shorter and looks simpler… and in fact it is. But I don’t recommend using it anymore. It’s just like using inline JavaScript. Using something like – that’s inline JavaScript – is highly discouraged nowadays (inline CSS is discouraged too, but that’s another topic).
However, the addEventListener() function, despite it’s the standard, just doesn’t work in old browsers (Internet Explorer below version 9), and this is another big difference. If you need to support these ancient browsers, you should follow the onclick way. But you could also use jQuery (or one of its alternatives): it basically simplifies your work and reduces the differences between browsers, therefore can save you a lot of time.
var clickEvent = document.getElementByID("onclick-eg");
var EventListener = document.getElementByID("addEventListener-eg");
clickEvent.onclick = function(){
window.alert("1 is not called")
}
clickEvent.onclick = function(){
window.alert("1 is not called, 2 is called")
}
EventListener.addEventListener("click",function(){
window.alert("1 is called")
})
EventListener.addEventListener("click",function(){
window.alert("2 is also called")
})
You can find a PCA function in the matplotlib module:
import numpy as np
from matplotlib.mlab import PCA
data = np.array(np.random.randint(10,size=(10,3)))
results = PCA(data)
results will store the various parameters of the PCA. It is from the mlab part of matplotlib, which is the compatibility layer with the MATLAB syntax
EDIT: on the blog nextgenetics I found a wonderful demonstration of how to perform and display a PCA with the matplotlib mlab module, have fun and check that blog!
function getRemote() {
return $.ajax({
type: "GET",
url: remote_url,
async: false,
success: function (result) {
/* if result is a JSon object */
if (result.valid)
return true;
else
return false;
}
});
}
Realize that this is an old question, but I wrote a plugin to address this issue that someone might find useful.
https://github.com/madbook/jquery.wait
lets you do this:
$('#myElement').addClass('load').wait(2000).addClass('done');
Here is one possible way. Use the exists
function to check for something unique in your util.R
code.
For example:
if(!exists("foo", mode="function")) source("util.R")
(Edited to include mode="function"
, as Gavin Simpson pointed out)
Since you are using jQuery you can use this onClick handler which calls click
:
$("#datepicker").click()
This is the same as $("#datepicker").trigger("click")
.
For a jQuery-free version check out this answer on SO.
Another approach to calculating working days is to use a WHILE loop which basically iterates through a date range and increment it by 1 whenever days are found to be within Monday – Friday. The complete script for calculating working days using the WHILE loop is shown below:
CREATE FUNCTION [dbo].[fn_GetTotalWorkingDaysUsingLoop]
(@DateFrom DATE,
@DateTo DATE
)
RETURNS INT
AS
BEGIN
DECLARE @TotWorkingDays INT= 0;
WHILE @DateFrom <= @DateTo
BEGIN
IF DATENAME(WEEKDAY, @DateFrom) IN('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday')
BEGIN
SET @TotWorkingDays = @TotWorkingDays + 1;
END;
SET @DateFrom = DATEADD(DAY, 1, @DateFrom);
END;
RETURN @TotWorkingDays;
END;
GO
Although the WHILE loop option is cleaner and uses less lines of code, it has the potential of being a performance bottleneck in your environment particularly when your date range spans across several years.
You can see more methods on how to calculate work days and hours in this article: https://www.sqlshack.com/how-to-calculate-work-days-and-hours-in-sql-server/
"Subscript out of range" indicates that you've tried to access an element from a collection that doesn't exist. Is there a "Sheet1" in your workbook? If not, you'll need to change that to the name of the worksheet you want to protect.

If you want to individually generate ddl for each object,
Queries are:
--GENERATE DDL FOR ALL USER OBJECTS
--1. FOR ALL TABLES
SELECT DBMS_METADATA.GET_DDL('TABLE', TABLE_NAME) FROM USER_TABLES;
--2. FOR ALL INDEXES
SELECT DBMS_METADATA.GET_DDL('INDEX', INDEX_NAME) FROM USER_INDEXES WHERE INDEX_TYPE ='NORMAL';
--3. FOR ALL VIEWS
SELECT DBMS_METADATA.GET_DDL('VIEW', VIEW_NAME) FROM USER_VIEWS;
OR
SELECT TEXT FROM USER_VIEWS
--4. FOR ALL MATERILIZED VIEWS
SELECT QUERY FROM USER_MVIEWS
--5. FOR ALL FUNCTION
SELECT DBMS_METADATA.GET_DDL('FUNCTION', OBJECT_NAME) FROM USER_PROCEDURES WHERE OBJECT_TYPE = 'FUNCTION'
===============================================================================================
GET_DDL Function doesnt support for some object_type like LOB,MATERIALIZED VIEW, TABLE PARTITION
SO, Consolidated query for generating DDL will be:
SELECT OBJECT_TYPE, OBJECT_NAME,DBMS_METADATA.GET_DDL(OBJECT_TYPE, OBJECT_NAME, OWNER)
FROM ALL_OBJECTS
WHERE (OWNER = 'XYZ') AND OBJECT_TYPE NOT IN('LOB','MATERIALIZED VIEW', 'TABLE PARTITION') ORDER BY OBJECT_TYPE, OBJECT_NAME;
You can pass a format string to the ToString method, like so:
ToString("N4"); // 4 decimal points Number

json.dump() will preserve the ordder of your dictionary. Open the file in a text editor and you will see. It will preserve the order regardless of whether you send it an OrderedDict.
But json.load() will lose the order of the saved object unless you tell it to load into an OrderedDict(), which is done with the object_pairs_hook parameter as J.F.Sebastian instructed above.
It would otherwise lose the order because under usual operation, it loads the saved dictionary object into a regular dict and a regular dict does not preserve the oder of the items it is given.
As I have experienced for the last 4 years, it will allow some one to easily identify whether the variable pointing a value/object or a jQuery wrapped DOM element
Ex:_x000D_
var name = 'jQuery';_x000D_
var lib = {name:'jQuery',version:1.6};_x000D_
_x000D_
var $dataDiv = $('#myDataDiv');
_x000D_
in the above example when I see the variable "$dataDiv" i can easily say that this variable pointing to a jQuery wrapped DOM element (in this case it is div). and also I can call all the jQuery methods with out wrapping the object again like $dataDiv.append(), $dataDiv.html(), $dataDiv.find() instead of $($dataDiv).append().
Hope it may helped. so finally want to say that it will be a good practice to follow this but not mandatory.
Will it work for you ?

Did you try df.groupby('id').head(2)
Ouput generated:

(Keep in mind that you might need to order/sort before, depending on your data)
EDIT: As mentioned by the questioner, use df.groupby('id').head(2).reset_index(drop=True)
to remove the multindex and flatten the results.

// Let's load the category Model and grab the product collection of that category
$product_collection = Mage::getModel('catalog/category')->load($categoryId)->getProductCollection();
// Now let's loop through the product collection and print the ID of every product
foreach($product_collection as $product) {
// Get the product ID
$product_id = $product->getId();
// Load the full product model based on the product ID
$full_product = Mage::getModel('catalog/product')->load($product_id);
// Now that we loaded the full product model, let's access all of it's data
// Let's get the Product Name
$product_name = $full_product->getName();
// Let's get the Product URL path
$product_url = $full_product->getProductUrl();
// Let's get the Product Image URL
$product_image_url = $full_product->getImageUrl();
// Let's print the product information we gathered and continue onto the next one
echo $product_name;
echo $product_image_url;
}
The only practical effect of the throw specifier is that if something different from myExc
is thrown by your function, std::unexpected
will be called (instead of the normal unhandled exception mechanism).
To document the kind of exceptions that a function can throw, I typically do this:
bool
some_func() /* throw (myExc) */ {
}
Let's say there is an administrator dashboard where users are listed with their id printed as a data attribute so it can be retrieved at some point via JavaScript.
An update could be executed this way …
class UserRepository extends \Doctrine\ORM\EntityRepository
{
public function updateUserStatus($userId, $newStatus)
{
return $this->createQueryBuilder('u')
->update()
->set('u.isActive', '?1')
->setParameter(1, $qb->expr()->literal($newStatus))
->where('u.id = ?2')
->setParameter(2, $qb->expr()->literal($userId))
->getQuery()
->getSingleScalarResult()
;
}
AJAX action handling:
# Post datas may be:
# handled with a specific custom formType — OR — retrieved from request object
$userId = (int)$request->request->get('userId');
$newStatus = (int)$request->request->get('newStatus');
$em = $this->getDoctrine()->getManager();
$r = $em->getRepository('NAMESPACE\User')
->updateUserStatus($userId, $newStatus);
if ( !empty($r) ){
# Row updated
}
Working example using Doctrine 2.5 (on top of Symfony3).
If you want implications, in some scenarios Google Chrome performance is horrible with hardware acceleration enabled. Oddly enough, changing the "trick" to -webkit-transform: rotateZ(360deg);
worked just fine.
I don't believe we ever figured out why.
@Autowired + @Qualifier will work only with spring DI, if you want to use some other DI in future @Resource is good option.
other difference which I found very significant is @Qualifier does not support dynamic bean wiring, as @Qualifier does not support placeholder, while @Resource does it very well.
For example: if you have an interface with multiple implementations like this
interface parent {
}
@Service("actualService")
class ActualService implements parent{
}
@Service("stubbedService")
class SubbedService implements parent{
}
with @Autowired & @Qualifier you need to set specific child implementation like
@Autowired
@Qualifier("actualService") or
@Qualifier("stubbedService")
Parent object;
which does not provide placeholder while with @Resource you can put placeholder and use property file to inject specific child implementation like
@Resource(name="${service.name}")
Parent object;
where service.name is set in property file as
#service.name=actualService
service.name=stubbedService
Hope that helps someone :)
There is a massive difference in the example you have posted, the first version:
var urls = await context.Urls.ToListAsync();
This is bad, it basically does select * from table
, returns all results into memory and then applies the where
against that in memory collection rather than doing select * from table where...
against the database.
The second method will not actually hit the database until a query is applied to the IQueryable
(probably via a linq .Where().Select()
style operation which will only return the db values which match the query.
If your examples were comparable, the async
version will usually be slightly slower per request as there is more overhead in the state machine which the compiler generates to allow the async
functionality.
However the major difference (and benefit) is that the async
version allows more concurrent requests as it doesn't block the processing thread whilst it is waiting for IO to complete (db query, file access, web request etc).
If you are using vim in MAC OSX, unfortunately it comes with older verion, and not complied with clipboard options. Luckily, homebrew can easily solve this problem.
install vim:
brew install vim
install gui verion of vim:
brew install macvim
restart the terminal to take effect.
append the following line to ~/.vimrc
set clipboard=unnamed
now you can copy the line in vim with yy
and paste it system-wide.
Updated Method:
I was never satisfied with set clipboard method for years. The biggest drawback is it will mess up your clipboard history, even when you use x
for deletion. Here is a better and more elegant solution.
Copy the text [range] of vim into the system clipboard. (Hint: use v
or V
to select the range first, and then type the colon :
to activate the Ex command):
:[line-range]yank +
e.g.,
:5,10y *
(copy/yank lines 5-10 to the system clipboard *
register)
Paste the content from the system clipboard into vim on a new line:
:put +
Note:
brew info vim
will be able to see other options for installing vim. Currrently it does not have any other options.You can use rsub, which is inspired on TextMate's rmate
. From the description:
Rsub is an implementation of TextMate 2's 'rmate' feature for Sublime Text 2, allowing files to be edited on a remote server using SSH port forwarding / tunnelling.
Here's a good tutorial on how to set it up properly.
I read this question looking for an answer, and didn't like any of them.
So I wrote a quick and dirty solution. Just put this somewhere on your sys.path, and it'll add any directory under folder
(from the current working directory), or under abspath
:
#using.py
import sys, os.path
def all_from(folder='', abspath=None):
"""add all dirs under `folder` to sys.path if any .py files are found.
Use an abspath if you'd rather do it that way.
Uses the current working directory as the location of using.py.
Keep in mind that os.walk goes *all the way* down the directory tree.
With that, try not to use this on something too close to '/'
"""
add = set(sys.path)
if abspath is None:
cwd = os.path.abspath(os.path.curdir)
abspath = os.path.join(cwd, folder)
for root, dirs, files in os.walk(abspath):
for f in files:
if f[-3:] in '.py':
add.add(root)
break
for i in add: sys.path.append(i)
>>> import using, sys, pprint
>>> using.all_from('py') #if in ~, /home/user/py/
>>> pprint.pprint(sys.path)
[
#that was easy
]
And I like it because I can have a folder for some random tools and not have them be a part of packages or anything, and still get access to some (or all) of them in a couple lines of code.
Reference the System.Web
dll in your model and use System.Web.Caching.Cache
public string[] GetNames()
{
string[] names = Cache["names"] as string[];
if(names == null) //not in cache
{
names = DB.GetNames();
Cache["names"] = names;
}
return names;
}
A bit simplified but I guess that would work. This is not MVC specific and I have always used this method for caching data.
I build the logic without using any built-in methods, please let me know any optimization or modifications. I tested in JS editor it is working fine.

I think this wont be true for all the cases. Because css will download parallel but js cant. Consider for the same case,
Instead of having single css, take 2 or 3 css files and try it out these ways,
1) css..css..js 2) css..js..css 3) js..css..css
I'm sure css..css..js will give better result than all others.
add semi-colon the line before:
$total_pages = ceil($total_result / $per_page);
fout=open("out.csv","a")
for num in range(1,201):
for line in open("sh"+str(num)+".csv"):
fout.write(line)
fout.close()
I had a problem when connecting my android phone, I couldn't charge my phone because the power switch on and then off ... PowerTop let me find this setting and was useful to fix the issue ( auto value was causing issue):

If you want to take input from user here is the code
If each string is given in new line:
strs = [input() for i in range(size)]
If the strings are separated by spaces:
strs = list(input().split())
You may have not set the output file.
My issue was that I called nltk.download('all')
as the root user, but the process that eventually used nltk was another user who didn't have access to /root/nltk_data where the content was downloaded.
So I simply recursively copied everything from the download location to one of the paths where NLTK was looking to find it like this:
cp -R /root/nltk_data/ /home/ubuntu/nltk_data
In the first case you are simply starting a new thread while in the second case you are entering in the thread pool.
The thread pool job is to share and recycle threads. It allows to avoid losing a few millisecond every time we need to create a new thread.
There are a several ways to enter the thread pool:
Ubuntu 17.10 default doesn't have the ~/.vimrc
file, we need create it and put the setting colorscheme color_scheme_name
in it.
By the way, colorscheme desert
is good scheme to choose.

Create a .bat

cd C:\ Path to your tomcat directory \ bin
startup.bat
Now on double-click, Tomcat server will start.
You can use Javascript.
For example, using jQuery:
$(':text').val('1000');
However, this won't be any different from using the value
attribute.
Does it have to be done in Java? I.e. does it need to be platform independent? If not, I'd suggest using the 'split' command in *nix. If you really wanted, you could execute this command via your java program. While I haven't tested, I imagine it perform faster than whatever Java IO implementation you could come up with.
Most are saying killall -9 dart

REST doesn't have a recommended date format. Really it boils down to what works best for your end user and your system. Personally, I would want to stick to a standard like you have for ISO 8601 (url encoded).
If not having ugly URI is a concern (e.g. not including the url encoded version of :
, -
, in you URI) and (human) addressability is not as important, you could also consider epoch time (e.g.
http://example.com/start/1331162374
). The URL looks a little cleaner, but you certainly lose readability.
The /2012/03/07
is another format you see a lot. You could expand upon that I suppose. If you go this route, just make sure you're either always in GMT time (and make that clear in your documentation) or you might also want to include some sort of timezone indicator.
Ultimately it boils down to what works for your API and your end user. Your API should work for you, not you for it ;-).
OS X tends to prefix the system account names with "_"; you don't say what version of OS X you're using, but at least in 10.8 and 10.9 the _postgres user exists in a default install. Note that you won't be able to su
to this account (except as root), since it doesn't have a password. sudo -u _postgres
, on the other hand, should work fine.

Very good and remarkable question with a very interesting discussion! I also was using the Array.sort()
function after pushing a single element in an array with some thousands of objects.
I had to extend your locationOf
function for my purpose because of having complex objects and therefore the need for a compare function like in Array.sort()
:
function locationOf(element, array, comparer, start, end) {
if (array.length === 0)
return -1;
start = start || 0;
end = end || array.length;
var pivot = (start + end) >> 1; // should be faster than dividing by 2
var c = comparer(element, array[pivot]);
if (end - start <= 1) return c == -1 ? pivot - 1 : pivot;
switch (c) {
case -1: return locationOf(element, array, comparer, start, pivot);
case 0: return pivot;
case 1: return locationOf(element, array, comparer, pivot, end);
};
};
// sample for objects like {lastName: 'Miller', ...}
var patientCompare = function (a, b) {
if (a.lastName < b.lastName) return -1;
if (a.lastName > b.lastName) return 1;
return 0;
};
Here we go.. We will need two classes. I am posting a code which changes mobile audio profile after each 5 seconds (5000 mili seconds) ...
Our 1st Class
public class ChangeProfileActivityMain extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Timer timer = new Timer();
TimerTask updateProfile = new CustomTimerTask(ChangeProfileActivityMain.this);
timer.scheduleAtFixedRate(updateProfile, 0, 5000);
}
}
Our 2nd Class
public class CustomTimerTask extends TimerTask {
private AudioManager audioManager;
private Context context;
private Handler mHandler = new Handler();
// Write Custom Constructor to pass Context
public CustomTimerTask(Context con) {
this.context = con;
}
@Override
public void run() {
// TODO Auto-generated method stub
// your code starts here.
// I have used Thread and Handler as we can not show Toast without starting new thread when we are inside a thread.
// As TimePicker has run() thread running., So We must show Toast through Handler.post in a new Thread. Thats how it works in Android..
new Thread(new Runnable() {
@Override
public void run() {
audioManager = (AudioManager) context.getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
mHandler.post(new Runnable() {
@Override
public void run() {
if(audioManager.getRingerMode() == AudioManager.RINGER_MODE_SILENT) {
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
Toast.makeText(context, "Ringer Mode set to Normal", Toast.LENGTH_SHORT).show();
} else {
audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
Toast.makeText(context, "Ringer Mode set to Silent", Toast.LENGTH_SHORT).show();
}
}
});
}
}).start();
}
}
In my case i have got a different solution in case any one need
yarn remove react-native-material-dropdown
Install new packages react-native-material-dropdown-v2
yarn add react-native-material-dropdown-v2
Replace react-native-material-dropdown with react-native-material-dropdown-v2 in your code
e.g. import { Dropdown } from 'react-native-material-dropdown' to import { Dropdown } from 'react-native-material-dropdown-v2'
another thing ==========
Another way this could be accomplished is by using the Start-Transcript
and Stop-Transcript
commands, respectively before and after command execution. This would capture the entire session including commands.
For this particular case Out-File
is probably your best bet though.
Try
os.path.getsize(filename)
It should return the size of a file, reported by os.stat().
I stumbled in here looking for a similar answer without the "git log" restriction. The answers here didn't give me what I needed but this did so I'll add it in case others find it useful:
git diff --name-only
You can also couple this with standard commit pointers to see what has changed since a particular commit:
git diff --name-only HEAD~3
git diff --name-only develop
git diff --name-only 5890e37..ebbf4c0
This succinctly provides file names only which is great for scripting. For example:
git diff --name-only develop | while read changed_file; do echo "This changed from the develop version: $changed_file"; done
#OR
git diff --name-only develop | xargs tar cvf changes.tar
Let's see:
#include <stdio.h>
#include <string.h>
int main()
{
char *p = "hello";
char q[] = "hello"; // no need to count this
printf("%zu\n", sizeof(p)); // => size of pointer to char -- 4 on x86, 8 on x86-64
printf("%zu\n", sizeof(q)); // => size of char array in memory -- 6 on both
// size_t strlen(const char *s) and we don't get any warnings here:
printf("%zu\n", strlen(p)); // => 5
printf("%zu\n", strlen(q)); // => 5
return 0;
}
foo* and foo[] are different types and they are handled differently by the compiler (pointer = address + representation of the pointer's type, array = pointer + optional length of the array, if known, for example, if the array is statically allocated), the details can be found in the standard. And at the level of runtime no difference between them (in assembler, well, almost, see below).
Also, there is a related question in the C FAQ:
Q: What is the difference between these initializations?
char a[] = "string literal"; char *p = "string literal";
My program crashes if I try to assign a new value to p[i].
A: A string literal (the formal term for a double-quoted string in C source) can be used in two slightly different ways:
- As the initializer for an array of char, as in the declaration of char a[] , it specifies the initial values of the characters in that array (and, if necessary, its size).
- Anywhere else, it turns into an unnamed, static array of characters, and this unnamed array may be stored in read-only memory, and which therefore cannot necessarily be modified. In an expression context, the array is converted at once to a pointer, as usual (see section 6), so the second declaration initializes p to point to the unnamed array's first element.
Some compilers have a switch controlling whether string literals are writable or not (for compiling old code), and some may have options to cause string literals to be formally treated as arrays of const char (for better error catching).

Using the awesome psutil
library it's pretty simple:
p = psutil.Process(pid)
p.terminate() #or p.kill()
If you don't want to install a new library, you can use the os
module:
import os
import signal
os.kill(pid, signal.SIGTERM) #or signal.SIGKILL
See also the os.kill
documentation.
If you are interested in starting the command python StripCore.py
if it is not running, and killing it otherwise, you can use psutil
to do this reliably.
Something like:
import psutil
from subprocess import Popen
for process in psutil.process_iter():
if process.cmdline() == ['python', 'StripCore.py']:
print('Process found. Terminating it.')
process.terminate()
break
else:
print('Process not found: starting it.')
Popen(['python', 'StripCore.py'])
Sample run:
$python test_strip.py #test_strip.py contains the code above
Process not found: starting it.
$python test_strip.py
Process found. Terminating it.
$python test_strip.py
Process not found: starting it.
$killall python
$python test_strip.py
Process not found: starting it.
$python test_strip.py
Process found. Terminating it.
$python test_strip.py
Process not found: starting it.
Note: In previous psutil
versions cmdline
was an attribute instead of a method.
First off, at the most detailed level, the problem can't be solved exactly. Years vary in length, and there isn't a clear "right choice" for year length.
That said, get the difference in whatever units are "natural" (probably seconds) and divide by the ratio between that and years. E.g.
delta_in_days / (365.25)
delta_in_seconds / (365.25*24*60*60)
...or whatever. Stay away from months, since they are even less well defined than years.
When converting datetime to integers one must keep in mind the tens, hundreds and thousands.... like "2018-11-03" must be like 20181103 in int for that you have to 2018*10000 + 100* 11 + 3
Similarly another example, "2018-11-03 10:02:05" must be like 20181103100205 in int
dt = datetime(2018,11,3,10,2,5)
print (dt)
#print (dt.timestamp()) # unix representation ... not useful when converting to int
print (dt.strftime("%Y-%m-%d"))
print (dt.year*10000 + dt.month* 100 + dt.day)
print (int(dt.strftime("%Y%m%d")))
print (dt.strftime("%Y-%m-%d %H:%M:%S"))
print (dt.year*10000000000 + dt.month* 100000000 +dt.day * 1000000 + dt.hour*10000 + dt.minute*100 + dt.second)
print (int(dt.strftime("%Y%m%d%H%M%S")))
To avoid that doing manually use below function
def datetime_to_int(dt):
return int(dt.strftime("%Y%m%d%H%M%S"))
You should take a look at Popcorn.js - a javascript framework for interacting with Html5 : http://popcornjs.org/documentation
When running the development server - which is what you get by running app.run()
, you get a single synchronous process, which means at most 1 request is being processed at a time.
By sticking Gunicorn in front of it in its default configuration and simply increasing the number of --workers
, what you get is essentially a number of processes (managed by Gunicorn) that each behave like the app.run()
development server. 4 workers == 4 concurrent requests. This is because Gunicorn uses its included sync
worker type by default.
It is important to note that Gunicorn also includes asynchronous workers, namely eventlet
and gevent
(and also tornado
, but that's best used with the Tornado framework, it seems). By specifying one of these async workers with the --worker-class
flag, what you get is Gunicorn managing a number of async processes, each of which managing its own concurrency. These processes don't use threads, but instead coroutines. Basically, within each process, still only 1 thing can be happening at a time (1 thread), but objects can be 'paused' when they are waiting on external processes to finish (think database queries or waiting on network I/O).
This means, if you're using one of Gunicorn's async workers, each worker can handle many more than a single request at a time. Just how many workers is best depends on the nature of your app, its environment, the hardware it runs on, etc. More details can be found on Gunicorn's design page and notes on how gevent works on its intro page.
Since printArea is a jQuery plugin it is not included in jquery.d.ts.
You need to create a jquery.printArea.ts definition file.
If you create a complete definition file for the plugin you may want to submit it to DefinitelyTyped.
Per the docs, you can catch the appropriate exception type (ClientErrorResponseException
for 4xx errors) and call its getResponse()
method to get the response object, then call getBody()
on that:
use Guzzle\Http\Exception\ClientErrorResponseException;
...
try {
$response = $request->send();
} catch (ClientErrorResponseException $exception) {
$responseBody = $exception->getResponse()->getBody(true);
}
Passing true
to the getBody
function indicates that you want to get the response body as a string. Otherwise you will get it as instance of class Guzzle\Http\EntityBody
.

I followed the below Steps. It worked for me.
In Jenkins execute shell under Build, creating a file and trying to push that file from Jenkins workspace to GitHub.
Download Git Publisher Plugin and Configure as shown below snapshot.
Click on Save and Build. Now you can check your git repository whether the file was pushed successfully or not.
I add a picture, show config
difference between mirror and bare.
The left is bare, right is mirror. You can be clear, mirror's config file have fetch
key, which means you can update it,by git remote update
or git fetch --all
The state should be managed in the parent component. You can transfer the open
value to the child component by adding a property.
class ParentComponent extends Component {
constructor(props) {
super(props);
this.state = {
open: false
};
this.toggleChildMenu = this.toggleChildMenu.bind(this);
}
toggleChildMenu() {
this.setState(state => ({
open: !state.open
}));
}
render() {
return (
<div>
<button onClick={this.toggleChildMenu}>
Toggle Menu from Parent
</button>
<ChildComponent open={this.state.open} />
</div>
);
}
}
class ChildComponent extends Component {
render() {
return (
<Drawer open={this.props.open}/>
);
}
}
The accepted answer in 2008 recommended SIGAR. However, as a comment from 2014 (@Alvaro) says:
Be careful when using Sigar, there are problems on x64 machines... Sigar 1.6.4 is crashing: EXCEPTION_ACCESS_VIOLATION and it seems the library doesn't get updated since 2010
My recommendation is to use https://github.com/oshi/oshi
Or the answer mentioned above.
Python lacks the tail recursion optimizations common in functional languages like lisp. In Python, recursion is limited to 999 calls (see sys.getrecursionlimit).
If 999 depth is more than you are expecting, check if the implementation lacks a condition that stops recursion, or if this test may be wrong for some cases.
I dare to say that in Python, pure recursive algorithm implementations are not correct/safe. A fib() implementation limited to 999 is not really correct. It is always possible to convert recursive into iterative, and doing so is trivial.
It is not reached often because in many recursive algorithms the depth tend to be logarithmic. If it is not the case with your algorithm and you expect recursion deeper than 999 calls you have two options:
1) You can change the recursion limit with sys.setrecursionlimit(n)
until the maximum allowed for your platform:
sys.setrecursionlimit(limit)
:Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python.
The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a crash.
2) You can try to convert the algorithm from recursive to iterative. If recursion depth is bigger than allowed by your platform, it is the only way to fix the problem. There are step by step instructions on the Internet and it should be a straightforward operation for someone with some CS education. If you are having trouble with that, post a new question so we can help.
The term for T&&
when used with type deduction (such as for perfect forwarding) is known colloquially as a forwarding reference. The term "universal reference" was coined by Scott Meyers in this article, but was later changed.
That is because it may be either r-value or l-value.
Examples are:
// template
template<class T> foo(T&& t) { ... }
// auto
auto&& t = ...;
// typedef
typedef ... T;
T&& t = ...;
// decltype
decltype(...)&& t = ...;
More discussion can be found in the answer for: Syntax for universal references
I had the same exception. My problem was that I had used:

[HttpGet]
public string Blah()

You can also check user by id
command.
id -u name
gives you the id of that user.
if the user doesn't exist, you got command return value ($?
)1
And as other answers pointed out: if all you want is just to check if the user exists, use if
with id
directly, as if
already checks for the exit code. There's no need to fiddle with strings, [
, $?
or $()
:
if id "$1" &>/dev/null; then
echo 'user found'
else
echo 'user not found'
fi
(no need to use -u
as you're discarding the output anyway)
Also, if you turn this snippet into a function or script, I suggest you also set your exit code appropriately:
#!/bin/bash
user_exists(){ id "$1" &>/dev/null; } # silent, it just sets the exit code
if user_exists "$1"; code=$?; then # use the function, save the code
echo 'user found'
else
echo 'user not found' >&2 # error messages should go to stderr
fi
exit $code # set the exit code, ultimately the same set by `id`
It's same as vikasdumca's steps, but thought to share the link.

Not an answer, but perhpas of interest. I did send a proposal to the CSS WG a few years ago. However, nothing has happened. If indeed they (and browser vendors) would see this as a genuine developer concern, perhaps the ball could start rolling?
In my case I had virtual dir. When I accessed main WCF Service in main dir it was working fine but accessing WCF service in virtual dir was throwing an error. I had following code in web.config for both main and virtual dir.
<security>
<requestFiltering>
<denyQueryStringSequences>
<add sequence=".." />
</denyQueryStringSequences>
</requestFiltering>
</security>
by removing from web.config in virtual dir it fixed it.
if you have multiple parameters use the syntax as below. I have a bat file with script as below:
start "dummyTitle" [/options] D:\path\ProgramName.exe Param1 Param2 Param3
start "dummyTitle" [/options] D:\path\ProgramName.exe Param4 Param5 Param6
This will open multiple consoles.
In case you need to use another profile, especially cross account. you need to add the profile in the config file
[profile profileName]
region = us-east-1
role_arn = arn:aws:iam::XXX:role/XXXX
source_profile = default
and then if you are accessing only a single file
aws s3 cp s3://crossAccountBucket/dir localdir --profile profileName
Did the same thing. Wasn't able to recreate Default Web Site directly - it kept complaining that the file already existed...
I fixed as follows:
select * from my_table where my_field Like '[a-z][a-z]%'
While searching for a solution to this problem, I found a variation on GONeale's answer through Patrick Desjardins' blog:
public int Update(T entity, Expression<Func<T, object>>[] properties)
{
DatabaseContext.Entry(entity).State = EntityState.Unchanged;
foreach (var property in properties)
{
var propertyName = ExpressionHelper.GetExpressionText(property);
DatabaseContext.Entry(entity).Property(propertyName).IsModified = true;
}
return DatabaseContext.SaveChangesWithoutValidation();
}
"As you can see, it takes as its second parameter an expression of a function. This will let use this method by specifying in a Lambda expression which property to update."
...Update(Model, d=>d.Name);
//or
...Update(Model, d=>d.Name, d=>d.SecondProperty, d=>d.AndSoOn);
( A somewhat similar solution is also given here: https://stackoverflow.com/a/5749469/2115384 )
The method I am currently using in my own code, extended to handle also (Linq) Expressions of type ExpressionType.Convert
. This was necessary in my case, for example with Guid
and other object properties. Those were 'wrapped' in a Convert() and therefore not handled by System.Web.Mvc.ExpressionHelper.GetExpressionText
.
public int Update(T entity, Expression<Func<T, object>>[] properties)
{
DbEntityEntry<T> entry = dataContext.Entry(entity);
entry.State = EntityState.Unchanged;
foreach (var property in properties)
{
string propertyName = "";
Expression bodyExpression = property.Body;
if (bodyExpression.NodeType == ExpressionType.Convert && bodyExpression is UnaryExpression)
{
Expression operand = ((UnaryExpression)property.Body).Operand;
propertyName = ((MemberExpression)operand).Member.Name;
}
else
{
propertyName = System.Web.Mvc.ExpressionHelper.GetExpressionText(property);
}
entry.Property(propertyName).IsModified = true;
}
dataContext.Configuration.ValidateOnSaveEnabled = false;
return dataContext.SaveChanges();
}

The PGOPTIONS
environment variable may be used to achieve this in a flexible way.
In an Unix shell:
PGOPTIONS="--search_path=my_schema_01" psql -d myDataBase -a -f myInsertFile.sql
If there are several invocations in the script or sub-shells that need the same options, it's simpler to set PGOPTIONS
only once and export it.
PGOPTIONS="--search_path=my_schema_01"
export PGOPTIONS
psql -d somebase
psql -d someotherbase
...
or invoke the top-level shell script with PGOPTIONS
set from the outside
PGOPTIONS="--search_path=my_schema_01" ./my-upgrade-script.sh
In Windows CMD environment, set PGOPTIONS=value
should work the same.
You are able to cut all odd/even columns by using seq:
This would print all odd columns
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 1 2 10)
To print all even columns you could use
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 2 2 10)
By changing the second number of seq you can specify which columns to be printed.
If the specification which columns to print is more complex you could also use a "one-liner-if-clause" like
echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(for i in $(seq 1 10); do if [[ $i -lt 10 && $i -lt 5 ]];then echo -n $i,; else echo -n $i;fi;done)
This would print all columns from 1 to 5 - you can simply modify the conditions to create more complex conditions to specify weather a column shall be printed.
The table is only dropped and re-created in cases where that's the only way SQL Server's Management Studio has been programmed to know how to do it.
There are certainly cases where it will do that when it doesn't need to, but there will also be cases where edits you make in Management Studio will not drop and re-create because it doesn't have to.
The problem is that enumerating all of the cases and determining which side of the line they fall on will be quite tedious.
This is why I like to use ALTER TABLE
in a query window, instead of visual designers that hide what they're doing (and quite frankly have bugs) - I know exactly what is going to happen, and I can prepare for cases where the only possibility is to drop and re-create the table (which is some number less than how often SSMS will do that to you).

Visual Studio Code has excellent search and replace capabilities across files. It is extremely fast, supports regex and live preview before replacement.
My personal understanding of the "nonlocal" statement (and do excuse me as I am new to Python and Programming in general) is that the "nonlocal" is a way to use the Global functionality within iterated functions rather than the body of the code itself. A Global statement between functions if you will.

Since Qt 5.5 you can use QTextStream::readLineInto
. It behaves similar to std::getline
and is maybe faster as QTextStream::readLine
, because it reuses the string:
QIODevice* device;
QTextStream in(&device);
QString line;
while (in.readLineInto(&line)) {
// ...
}
It seems that your
$(".modal").on('shown.bs.modal') // One way Or
You can do this in a slight different way, like this
$('.btn').click(function(){
// Send the src on click of button to the iframe. Which will make it load.
$(".openifrmahere").find('iframe').attr("src","http://www.hf-dev.info");
$('.modal').modal({show:true});
// Hide the loading message
$(".openifrmahere").find('iframe').load(function() {
$('.loading').hide();
});
})
I think the easiest route is to include the jQuery javascript library in your webpages, then use JSON as format to pass data between the two.
In your HTML pages, you can request data from the PHP scripts like this:
$.getJSON('http://foo/bar.php', {'num1': 12, 'num2': 27}, function(e) {
alert('Result from PHP: ' + e.result);
});
In bar.php you can do this:
$num1 = $_GET['num1'];
$num2 = $_GET['num2'];
echo json_encode(array("result" => $num1 * $num2));
This is what's usually called AJAX, and it is useful to give web pages a more dynamic and desktop-like feel (you don't have to refresh the entire page to communicate with PHP).
Other techniques are simpler. As others have suggested, you can simply generate the variable data from your PHP script:
$foo = 123;
echo "<script type=\"text/javascript\">\n";
echo "var foo = ${foo};\n";
echo "alert('value is:' + foo);\n";
echo "</script>\n";
Most web pages nowadays use a combination of the two.
Use org.junit.Assert's method assertArrayEquals
:
import org.junit.Assert;
...
Assert.assertArrayEquals( expectedResult, result );
If this method is not available, you may have accidentally imported the Assert class from junit.framework
.
For a list of elements
List<string> lstTest = new List<string>();
lstTest.Add("test1");
lstTest.Add("test2");
lstTest.Add("test3");
lstTest.Add("test4");
lstTest.Add("test5");
lstTest.Add("test6");
If you want to copy all the elements
List<string> lstNew = new List<string>();
lstNew.AddRange(lstTest);
If you want to copy the first 3 elements
List<string> lstNew = lstTest.GetRange(0, 3);
Do you want to find elements that contain "match", or that equal "match"?
This will find elements that have text nodes that equal 'match' (matches none of the elements because of leading and trailing whitespace in random2
):
//*[text()='match']
This will find all elements that have text nodes that equal "match", after removing leading and trailing whitespace(matches random2
):
//*[normalize-space(text())='match']
This will find all elements that contain 'match' in the text node value (matches random2
and random3
):
//*[contains(text(),'match')]
This XPATH 2.0 solution uses the matches()
function and a regex pattern that looks for text nodes that contain 'match' and begin at the start of the string(i.e. ^
) or a word boundary (i.e. \W
) and terminated by the end of the string (i.e. $
) or a word boundary. The third parameter i
evaluates the regex pattern case-insensitive. (matches random2
)
//*[matches(text(),'(^|\W)match($|\W)','i')]
Reflection is a key mechanism to allow an application or framework to work with code that might not have even been written yet!
Take for example your typical web.xml file. This will contain a list of servlet elements, which contain nested servlet-class elements. The servlet container will process the web.xml file, and create new a new instance of each servlet class through reflection.
Another example would be the Java API for XML Parsing (JAXP). Where an XML parser provider is 'plugged-in' via well-known system properties, which are used to construct new instances through reflection.
And finally, the most comprehensive example is Spring which uses reflection to create its beans, and for its heavy use of proxies
If I understand correctly, you need to convert the type (char value) that you store in Building list to the type (enum) that you store in buildingStatus list.
(For each status in the Building list//character value//, does the status exists in the buildingStatus list//enum value//)
public static IQueryable<Building> WithStatus(this IQueryable<Building> qry,
IList<BuildingStatuses> buildingStatus)
{
return from v in qry
where ContainsStatus(v.Status)
select v;
}
private bool ContainsStatus(v.Status)
{
foreach(Enum value in Enum.GetValues(typeof(buildingStatus)))
{
If v.Status == value.GetCharValue();
return true;
}
return false;
}
I know you are not after array_unique()
. However, you will not find a magical obvious function nor will writing one be faster than making use of the native functions.
I propose:
function array_has_dupes($array) {
// streamline per @Felix
return count($array) !== count(array_unique($array));
}
Adjust the second parameter of array_unique()
to meet your comparison needs.
One thing you can do is, you might have subfolders for each projects. So, install mongoose in that subfolders and require() mongoose from own folders in each sub applications. Not from the project root or from global. So one sub project, one mongoose installation and one mongoose instance.
-app_root/
--foo_app/
---db_access.js
---foo_db_connect.js
---node_modules/
----mongoose/
--bar_app/
---db_access.js
---bar_db_connect.js
---node_modules/
----mongoose/
In foo_db_connect.js
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/foo_db');
module.exports = exports = mongoose;
In bar_db_connect.js
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/bar_db');
module.exports = exports = mongoose;
In db_access.js files
var mongoose = require("./foo_db_connect.js"); // bar_db_connect.js for bar app
Now, you can access multiple databases with mongoose.
You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.*
function are thin wrappers that basically do gca().*
.
plt.subplot
returns an axes
object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.
import matplotlib.pyplot as plt
ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])
ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])
and so on for as many axes as you want.
or better, wrap it all up in a loop:
import matplotlib.pyplot as plt
DATA_x = ([1, 2],
[2, 3],
[3, 4])
DATA_y = DATA_x[::-1]
XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3
for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
ax = plt.subplot(1, 3, j + 1)
ax.scatter(x, y)
ax.set_xlim(xlim)
ax.set_ylim(ylim)
It depends on what the problem with the arguments is.
If the argument has the wrong type, raise a TypeError. For example, when you get a string instead of one of those Booleans.
if not isinstance(save, bool):
raise TypeError(f"Argument save must be of type bool, not {type(save)}")
Note, however, that in Python we rarely make any checks like this. If the argument really is invalid, some deeper function will probably do the complaining for us. And if we only check the boolean value, perhaps some code user will later just feed it a string knowing that non-empty strings are always True. It might save him a cast.
If the arguments have invalid values, raise ValueError. This seems more appropriate in your case:
if recurse and not save:
raise ValueError("If recurse is True, save should be True too")
Or in this specific case, have a True value of recurse imply a True value of save. Since I would consider this a recovery from an error, you might also want to complain in the log.
if recurse and not save:
logging.warning("Bad arguments in import_to_orm() - if recurse is True, so should save be")
save = True
You can use fetch optionally with await-try-catch
let photo = document.getElementById("image-file").files[0];
let formData = new FormData();
formData.append("photo", photo);
fetch('/upload/image', {method: "POST", body: formData});
async function SavePhoto(inp)
{
let user = { name:'john', age:34 };
let formData = new FormData();
let photo = inp.files[0];

SUMMARY
filename
formData parameter.Content-Type
to multipart/form-data
- this will be set automatically by browser./upload/image
you can use full address like http://.../upload/image
.multiple
attribute: <input multiple type=... />
, and attach all chosen files to formData in similar way (e.g. photo2=...files[2];
... formData.append("photo2", photo2);
)let user = {name:'john', age:34}
in this way: formData.append("user", JSON.stringify(user));
fetch
using AbortController
, for old approach by xhr.timeout= milisec
I followed many links including the official documentation, however it all ended up in this error:
Requires: container-selinux >= 2.9
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
The only way it worked for me is as follows (yum upgrade
worked I guess):
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
yum upgrade docker-ce
You don't need --header "Content-Length: $LENGTH".
curl --request POST --data-binary "@template_entry.xml" $URL
Note that GET request does not support content body widely.
Also remember that POST request have 2 different coding schema. This is first form:
$ nc -l -p 6666 & $ curl --request POST --data-binary "@README" http://localhost:6666 POST / HTTP/1.1 User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6 Host: localhost:6666 Accept: */* Content-Length: 9309 Content-Type: application/x-www-form-urlencoded Expect: 100-continue .. -*- mode: rst; coding: cp1251; fill-column: 80 -*- .. rst2html.py README README.html .. contents::
You probably request this:
-F/--form name=content (HTTP) This lets curl emulate a filled-in form in which a user has pressed the submit button. This causes curl to POST data using the Content- Type multipart/form-data according to RFC2388. This enables uploading of binary files etc. To force the 'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload, while the < makes a text field and just get the contents for that text field from a file.
You have a couple of questions here, so I'll address them separately:
My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).
You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:
Base table (what you have now):
| id primary_key sequence
| -- other columns here.
Items table:
| id primary_key sequence
| descript VARCHAR(30) UNIQUE
Map table:
| base_id bigint
| items_id bigint
Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.
And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.
If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.
Personally, I would use TEXT
. It does not sound like you'd gain much by making this a BLOB
, and TEXT
, in my experience, is easier to read if you're using some form of IDE.
Another library to consider is MySqlConnector, https://mysqlconnector.net/. Mysql.Data is under a GPL license, whereas MySqlConnector is MIT.
There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:
http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html
jquery resolved this for me with its .append() function - used this to load the complete jquery ui package
/*
* FILENAME : project.library.js
* USAGE : loads any javascript library
*/
var dirPath = "../js/";
var library = ["functions.js","swfobject.js","jquery.jeditable.mini.js","jquery-ui-1.8.8.custom.min.js","ui/jquery.ui.core.min.js","ui/jquery.ui.widget.min.js","ui/jquery.ui.position.min.js","ui/jquery.ui.button.min.js","ui/jquery.ui.mouse.min.js","ui/jquery.ui.dialog.min.js","ui/jquery.effects.core.min.js","ui/jquery.effects.blind.min.js","ui/jquery.effects.fade.min.js","ui/jquery.effects.slide.min.js","ui/jquery.effects.transfer.min.js"];
for(var script in library){
$('head').append('<script type="text/javascript" src="' + dirPath + library[script] + '"></script>');
}
To Use - in the head of your html/php/etc after you import jquery.js you would just include this one file like so to load in the entirety of your library appending it to the head...
<script type="text/javascript" src="project.library.js"></script>
Two years late, but I have the solution you're looking for. Not intending to take credit form the original author, here's a plugin which I found works exceptionally well for what you need, but gets all possible styles in all browsers, even IE.
Warning: This code generates a lot of output, and should be used sparingly. It not only copies all standard CSS properties, but also all vendor CSS properties for that browser.
jquery.getStyleObject.js:
/*
* getStyleObject Plugin for jQuery JavaScript Library
* From: http://upshots.org/?p=112
*/
(function($){
$.fn.getStyleObject = function(){
var dom = this.get(0);
var style;
var returns = {};
if(window.getComputedStyle){
var camelize = function(a,b){
return b.toUpperCase();
};
style = window.getComputedStyle(dom, null);
for(var i = 0, l = style.length; i < l; i++){
var prop = style[i];
var camel = prop.replace(/\-([a-z])/g, camelize);
var val = style.getPropertyValue(prop);
returns[camel] = val;
};
return returns;
};
if(style = dom.currentStyle){
for(var prop in style){
returns[prop] = style[prop];
};
return returns;
};
return this.css();
}
})(jQuery);
Basic usage is pretty simple, but he's written a function for that as well:
$.fn.copyCSS = function(source){
var styles = $(source).getStyleObject();
this.css(styles);
}
Hope that helps.
private String encodeFileToBase64Binary(File file){
String encodedfile = null;
try {
FileInputStream fileInputStreamReader = new FileInputStream(file);
byte[] bytes = new byte[(int)file.length()];
fileInputStreamReader.read(bytes);
encodedfile = Base64.encodeBase64(bytes).toString();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return encodedfile;
}
Should work.
Here's a working example:
Excerpt:
function loadIframe(iframeName, url) {
var $iframe = $('#' + iframeName);
if ($iframe.length) {
$iframe.attr('src',url);
return false;
}
return true;
}
This is one way to do it:
string = "this is a string"
ssplit = string.split()
for word in ssplit:
print (word)
Output:
this
is
a
string
The idea of retrying the query in case of Deadlock exception is good, but it can be terribly slow, since mysql query will keep waiting for locks to be released. And incase of deadlock mysql is trying to find if there is any deadlock, and even after finding out that there is a deadlock, it waits a while before kicking out a thread in order to get out from deadlock situation.
What I did when I faced this situation is to implement locking in your own code, since it is the locking mechanism of mysql is failing due to a bug. So I implemented my own row level locking in my java code:
private HashMap<String, Object> rowIdToRowLockMap = new HashMap<String, Object>();
private final Object hashmapLock = new Object();
public void handleShortCode(Integer rowId)
{
Object lock = null;
synchronized(hashmapLock)
{
lock = rowIdToRowLockMap.get(rowId);
if (lock == null)
{
rowIdToRowLockMap.put(rowId, lock = new Object());
}
}
synchronized (lock)
{
// Execute your queries on row by row id
}
}

from a1 as x
JOIN a2 as y ON (x.weddingTable = y.weddingTable) AND (x.tableSeat = y. tableSeat);

function checkIfKeysExist($array, $mustHaveKeys, &$missingKeys = array()) {
// extract the keys of $array as an array

I am assuming you need to check for multiple keys ALL EXIST in an array. If you are looking for a match of at least one key, let me know so I can provide another function.

I have just written an app which can make a call from a web page - I don't know if this is any use to you, but I include anyway:
in your onCreate you'll need to use a webview and assign a WebViewClient, as below:
browser = (WebView) findViewById(R.id.webkit);
browser.setWebViewClient(new InternalWebViewClient());
then handle the click on a phone number like this:
private class InternalWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.indexOf("tel:") > -1) {
startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
return true;
} else {
return false;
}
}
}
Let me know if you need more pointers.

String value = item.getValue();

Another option is to transfer stored procedures using SQL Server Integration Services (SSIS). There is a task called Transfer SQL Server Objects Task. You can use the task to transfer the following items:
It's a graphical tutorial for Transfer SQL Server Objects Task.
Following @GregaKešpret you can make an infix operator:
`%+=%` = function(e1,e2) eval.parent(substitute(e1 <- e1 + e2))
x = 1
x %+=% 2 ; x
You May use first split and rejoin it using white space. it will work sure.
String[] Larray = L.split("[\\n]+");
L = "";
for(int i = 0; i<Larray.lengh; i++){
L = L+" "+Larray[i];
}
You will want to use a CONVERT() statement.
Try the following;
SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....
See MSDN Cast and Convert for more information.
Hope this piece of code give you an idea of changing jPanels inside a JFrame.
public class PanelTest extends JFrame {
Container contentPane;
public PanelTest() {
super("Changing JPanel inside a JFrame");
contentPane=getContentPane();
}
public void createChangePanel() {
contentPane.removeAll();
JPanel newPanel=new JPanel();
contentPane.add(newPanel);
System.out.println("new panel created");//for debugging purposes
validate();
setVisible(true);
}
}
It may be too late for my answer, but I think this is not that hard. You can extend the PDFTextStripper class and override the writePage() and processTextPosition(...) methods. In your case I assume that the column headers are always the same. That means that you know the x-coordinate of each column heading and you can compare the the x-coordinate of the numbers to those of the column headings. If they are close enough (you have to test to decide how close) then you can say that that number belongs to that column.
Another approach would be to intercept the "charactersByArticle" Vector after each page is written:
@Override
public void writePage() throws IOException {
super.writePage();
final Vector<List<TextPosition>> pageText = getCharactersByArticle();
//now you have all the characters on that page
//to do what you want with them
}
Knowing your columns, you can do your comparison of the x-coordinates to decide what column every number belongs to.
The reason you don't have any spaces between numbers is because you have to set the word separator string.
I hope this is useful to you or to others who might be trying similar things.

In AndroidManifest.xml
worked for me on Android Studio(Beta)0.8.2.
The shorter ones are vectorized, meaning they can return a vector, like this:
((-2:2) >= 0) & ((-2:2) <= 0)
# [1] FALSE FALSE TRUE FALSE FALSE
The longer form evaluates left to right examining only the first element of each vector, so the above gives
((-2:2) >= 0) && ((-2:2) <= 0)
# [1] FALSE
As the help page says, this makes the longer form "appropriate for programming control-flow and [is] typically preferred in if clauses."
So you want to use the long forms only when you are certain the vectors are length one.
You should be absolutely certain your vectors are only length 1, such as in cases where they are functions that return only length 1 booleans. You want to use the short forms if the vectors are length possibly >1. So if you're not absolutely sure, you should either check first, or use the short form and then use all
and any
to reduce it to length one for use in control flow statements, like if
.
The functions all
and any
are often used on the result of a vectorized comparison to see if all or any of the comparisons are true, respectively. The results from these functions are sure to be length 1 so they are appropriate for use in if clauses, while the results from the vectorized comparison are not. (Though those results would be appropriate for use in ifelse
.
One final difference: the &&
and ||
only evaluate as many terms as they need to (which seems to be what is meant by short-circuiting). For example, here's a comparison using an undefined value a
; if it didn't short-circuit, as &
and |
don't, it would give an error.
a
# Error: object 'a' not found
TRUE || a
# [1] TRUE
FALSE && a
# [1] FALSE
TRUE | a
# Error: object 'a' not found
FALSE & a
# Error: object 'a' not found

if you have error in Sqlite built in python you can use Conda to solve this conflict

You can achieve this more universally by applying the following CSS:
html,
body {
height: 100%;
width: 100%;
overflow: auto;
}
This allows your content, whatever it is, to become scrollable within body
, but be aware that the scrolling context where scroll
event is fired is now document.body
, not window
.
Linq has a Max function.
If you have an IEnumerable<int>
you can call this directly, but if you require these in separate parameters you could create a function like this:
using System.Linq;
...
static int Max(params int[] numbers)
{
return numbers.Max();
}
Then you could call it like this: max(1, 6, 2)
, it allows for an arbitrary number of parameters.
You could change /etc/mongod.conf

ListenForClients

Alternative way: use the command interface!
Cmd/Ctrl + Shift + P ? Python: Select Interpreter ? choose the one with the packages you look for:
Any JS code which executes and deals with DOM elements should execute after the DOM elements have been created. JS code is interpreted from top to down as layed out in the HTML. So, if there is a tag before the DOM elements, the JS code within script tag will execute as the browser parses the HTML page.
So, in your case, you can put your DOM interacting code inside a function so that only function is defined but not executed.
Then you can add an event listener for document load to execute the function.
That will give you something like:
<script>
function init() {
var myButton = document.getElementById("myButton");
var myTextfield = document.getElementById("myTextfield");
myButton.onclick = function() {
var userName = myTextfield.value;
greetUser(userName);
}
}
function greetUser(userName) {
var greeting = "Hello " + userName + "!";
document.getElementsByTagName ("h2")[0].innerHTML = greeting;
}
document.addEventListener('readystatechange', function() {
if (document.readyState === "complete") {
init();
}
});
</script>

Another option for the selection of the desired entries is to use map
:
df.loc[(df == 1).any(axis=1), df.columns.map(lambda x: x.startswith('foo'))]
which gives you all the columns for rows that contain a 1
:
foo.aa foo.bars foo.fighters foo.fox foo.manchu
0 1.0 0 0 2 NA
1 2.1 0 1 4 0
2 NaN 0 NaN 1 0
5 6.8 1 0 5 0
The row selection is done by
(df == 1).any(axis=1)
as in @ajcr's answer which gives you:
0 True
1 True
2 True
3 False
4 False
5 True
dtype: bool
meaning that row 3
and 4
do not contain a 1
and won't be selected.
The selection of the columns is done using Boolean indexing like this:
df.columns.map(lambda x: x.startswith('foo'))
In the example above this returns
array([False, True, True, True, True, True, False], dtype=bool)
So, if a column does not start with foo
, False
is returned and the column is therefore not selected.
If you just want to return all rows that contain a 1
- as your desired output suggests - you can simply do
df.loc[(df == 1).any(axis=1)]
which returns
bar.baz foo.aa foo.bars foo.fighters foo.fox foo.manchu nas.foo
0 5.0 1.0 0 0 2 NA NA
1 5.0 2.1 0 1 4 0 0
2 6.0 NaN 0 NaN 1 0 1
5 6.8 6.8 1 0 5 0 0
You could probably use an inheritance structure although the more I played with this the dirtier I felt.

This is a FAQ:
//someName[3]
means: all someName
elements in the document, that are the third someName
child of their parent -- there may be many such elements.
What you want is exactly the 3rd someName
element:
(//someName)[3]
Explanation: the []
has a higher precedence (priority) than //
. Remember always to put expressions of the type //someName
in brackets when you need to specify the Nth node of their selected node-list.
It could be that one or two of your columns may have a factor in them, or what is more likely is that your columns may be formatted as factors. Please would you give str(col1) and str(col2) a try? That should tell you what format those columns are in.
I am unsure if you're trying to add the rows of a column to produce a new column or simply all of the numbers in both columns to get a single number.
length is constant which is used to find out the array storing capacity not the number of elements in the array
Example:
int[] a = new int[5]
a.length
always returns 5, which is called the capacity of an array. But
number of elements in the array is called size
Example:
int[] a = new int[5]
a[0] = 10
Here the size would be 1, but a.length
is still 5. Mind that there is no actual property or method called size
on an array so you can't just call a.size
or a.size()
to get the value 1.
The size()
method is available for collections, length
works with arrays in Java.
You just need to wrap object in ()
var arr = [{_x000D_
id: 1,_x000D_
name: 'bill'_x000D_
}, {_x000D_
id: 2,_x000D_
name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)
_x000D_

Everything in /var/lib/docker are filesystems of containers. If you stop all your containers and prune them, you should end up with the folder being empty. You probably don't really want that, so don't go randomly deleting stuff in there. Do not delete things in /var/lib/docker directly. You may get away with it sometimes, but it's inadvisable for so many reasons.
Do this instead:
sudo bash
cd /var/lib/docker
find . -type f | xargs du -b | sort -n
What you will see is the largest files shown at the bottom. If you want, figure out what containers those files are in, enter those containers with docker exec -ti containername -- /bin/sh
and delete some files.
You can also put docker system prune -a -f
on a daily/weekly cron job as long as you aren't leaving stopped containers and volumes around that you care about. It's better to figure out the reasons why it's growing, and correct them at the container level.

LinkedHashMap
is precisely what you're looking for.
It is exactly like HashMap
, except that when you iterate over it, it presents the items in the insertion order.
If you cannot see the "ng serve" command running, then you can do the following on Mac OSX (This should work on any Linux and Uni software as well).
ps -ef | grep "ng serve"
From this, find out the PID of the process and then kill it with the following command.
kill -9 <PID>
A GUID is a 16-byte (128-bit) number, typically represented by a 32-character hexadecimal string. A GUID (in hex form) need not contain any alpha characters, though by chance it probably would. If you are targeting a GUID in hex form, you can check that the string is 32-characters long (after stripping dashes and curly brackets) and has only letters A-F and numbers.
There is certain style of presenting GUIDs (dash-placement) and regular expressions can be used to check for this, e.g.,
@"^(\{{0,1}([0-9a-fA-F]){8}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){4}-([0-9a-fA-F]){12}\}{0,1})$"
from http://www.geekzilla.co.uk/view8AD536EF-BC0D-427F-9F15-3A1BC663848E.htm. That said, it should be emphasized that the GUID really is a 128-bit number and could be represented in a number of different ways.
You may need a plugin to do this. You can try the command line cc.ddl
(delete duplicate lines) of ConyEdit. It is a cross-editor plugin for the text editors, including Notepad++.
With ConyEdit running in background, follow the steps below:
cc.ddl
at the end of the text. edit: I guess it's now starting to be safe to use the native JSON.stringify() method, supported by most browsers (yes, even IE8+ if you're wondering).
As simple as:
JSON.stringify(yourData)
You should encode you data in JSON before sending it, you can't just send an object like this as POST data.
I recommand using the jQuery json plugin to do so. You can then use something like this in jQuery:
$.post(_saveDeviceUrl, {
data : $.toJSON(postData)
}, function(response){
//Process your response here
}
);
Code ${1:-/dev/stdin}
will just understand first argument, so, how about this.
ARGS='$*'
if [ -z "$*" ]; then
ARGS='-'
fi
eval "cat -- $ARGS" | while read line
do
echo "$line"
done
You can use:
<script type="text/javascript">
function prepareFrame() {
var ifrm = document.createElement("iframe");
ifrm.setAttribute("src", "http://google.com/");
ifrm.style.width = "640px";
ifrm.style.height = "480px";
document.body.appendChild(ifrm);
}
</script>

I am using this solution that works perfectly for me in Python 3
import logging
log = logging.getLogger(__name__)
...
def deep_compare(self,left, right, level=0):
if type(left) != type(right):
log.info("Exit 1 - Different types")
return False
elif type(left) is dict:
# Dict comparison
for key in left:
if key not in right:
log.info("Exit 2 - missing {} in right".format(key))
return False
else:
if not deep_compare(left[str(key)], right[str(key)], level +1 ):
log.info("Exit 3 - different children")
return False
return True
elif type(left) is list:
# List comparison
for key in left:
if key not in right:
log.info("Exit 4 - missing {} in right".format(key))
return False
else:
if not deep_compare(left[left.index(key)], right[right.index(key)], level +1 ):
log.info("Exit 5 - different children")
return False
return True
else:
# Other comparison
return left == right
return False
It compares dict, list and any other types that implements the "==" operator by themselves. If you need to compare something else different, you need to add a new branch in the "if tree".
Hope that helps.
If you have a list of lists, you only needed to use ...
import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)
per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.
EDIT
another way to deal with duplicate is you can do like this
var dic = slist.Select((element, index)=> new{element,index} )
.ToDictionary(ele=>ele.index.ToString(), ele=>ele.element);
or
easy way to do is
var res = list.ToDictionary(str => str, str=> str);
but make sure that there is no string is repeating...again otherewise above code will not work for you
if there is string is repeating than its better to do like this
Dictionary<string,string> dic= new Dictionary<string,string> ();
foreach(string s in Stringlist)
{
if(!dic.ContainsKey(s))
{
// dic.Add( value to dictionary
}
}
Despite that the other answers are correct and thoroughly explained, I found some difficulties understanding them. Here is the method I used (Taken from here):
openssl pkcs12 -in filename.pfx -out cert.pem -nodes
Extracts the private key form a PFX to a PEM file:
openssl pkcs12 -in filename.pfx -nocerts -out key.pem
Exports the certificate (includes the public key only):
openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
Removes the password (paraphrase) from the extracted private key (optional):
openssl rsa -in key.pem -out server.key
Use the .val()
method to get the actual value of the element you need.
